Visit our showroom in Alcamo (TP) - Italy to take a closer look or try out our diamond jewellery that you have found online. Our specialists will help you in your exciting search for a piece of jewellery that suits you perfectly. In all discretion, you will be guided through the selection of jewellery you have found online and the purchase of your jewellery. You will get to know the specificities of Diamante Sicuro in a pleasant atmosphere.

The collections are to be seen and you can try everything you like. Please note that our showrooms receive mainly by appointment. To make an appointment please contact the showroom directly.

A visit to our showroom is by appointment only. In most cases it is not possible to take the jewellery with you immediately if you decide to buy it during the visit, as we start the production process of our diamond jewellery once we have received payment. Thanks to this production on request, we are able to supply high quality diamond jewellery at an exceptional price/quality ratio. After receiving the payment, our craftsmen in Valencia produce your handmade diamond jewellery. This allows us to offer the high quality craftsmanship that Diamante Sicuro represents. By creating unique handmade jewellery, we can finish the jewel in much more detail and achieve a clearly visible higher quality than a mass produced jewel. The production process of a jewel listed on www.diamante-sicuro.com usually takes 1-10 working days, depending on the specific design and material. For a custom-made design jewel, you need to calculate approximately up to 3 working weeks. However, in very few cases, the jewel or loose diamond is in stock in the showroom, and can be taken with you immediately after we have received payment.

During the production process, you will always be up to date on each step. An expected delivery date will be communicated to you as soon as the jewel is ready for quality control.

Once the production process is complete, we can ship the jewellery with insured shipping to an address of your choice, or you can collect the jewellery from our showroom.

Diamante Sicuro offers only 100% natural diamonds. This means that these diamonds are not treated, artificial or intensified for purity.

Diamante Sicuro only works with the world's most renowned diamond industry certificates: GIA, HRD and IGI.

Diamante Sicuro has a zero tolerance policy towards conflict diamonds. We only purchase diamonds through the most respected diamond producers.

The diamonds we select are of high quality and offer maximum brilliance in proportion to their cost.

We select diamonds that shine to the highest brilliance but do not pay any additional cost for prestige or rarity. Generally the diamonds used by Diamante Sicuro have a VS or SI score on the purity scale, and have an F or H colour.

Diamonds with this score have only minor impurities, impossible for a consumer to see with the naked eye.

Diamonds with this result have a beautiful white colour without yellow shades.

  1. Colour and clarity

Diamante Sicuro offers 2 possible quality combinations:

Colour F/G - clarity VS

Colour G/H - clarity YES

Both combinations guarantee a diamond of a beautiful white colour without yellow shades. VS diamonds contain inclusions not perceptible to the naked eye. With SI diamonds the inclusions may be slightly distinguishable, but only under certain conditions. In addition, all diamonds we select have great brilliance due to their high score in terms of cut quality.

The first combination (F/G-VS) will be a little brighter than the second, due to the difference in colour and purity.

  1. Cut

As regards the degree of cut, we can distinguish different parameters, depending on the shape of the diamond:

      a. Round diamonds

In this case the cut has three parameters:




      b. Other shapes (princess, oval, pillow, etc.)

All other shapes of diamonds (excluding round diamonds) have two parameters in terms of cut:



Diamante Sicuro not only selects its diamonds according to the 4 Cs you find on the diamond certificate, but judges the quality of the light produced. As our headquarters is located in the heart of the world centre of diamonds, we can carefully check every diamond. In the end we select the diamonds according to the light they radiate. In other words, we only work with diamonds that shine better than the theoretical properties of their certificate (4 C).

The combination of our know-how and methods and the fact that prices in the diamond industry are based on the 4 Cs allows us to offer the best value for money. Only diamonds with the highest brilliance will be chosen. The brightness of a diamond is the result of the white light, the movement of light and the coloured light that it reflects.

Diamonds are placed in jewellery in a specific way, so that the table (the flat top of the diamond) is visible. The lower part of the diamond, which ends in a cone, is usually not visible. For example, in a ring, the lower part disappears inside the ring. In this way, light enters the diamond only from the top of the stone. Because of the specific refraction of the light from the diamonds and the mirror effect of the lower sides, the light will come back out of the top of the diamond in all the colours of the rainbow. This process is only maximised if the diamond is cut perfectly, has perfect proportions and all corners and sides have been cut according to the 58-sided mathematical model.

The diamond will only shine at its best if the light is controlled. Otherwise the light will be lost or disappear in another corner of the diamond.

The cutting process is obviously a very difficult, risky and time-consuming process and requires years of experience. Since all the diamond growth ribs are not visible, the work cannot be computerised, and is always done by hand. Years of training are required.

In our showroom you can find diamonds of any shape and size: round, princess (square), pear (teardrop) and many others on request.

The quality of diamonds translates into the 4 C's. When you want to buy diamonds, the 4 C's are essential to determine the quality of your investment or your diamond jewellery.

  • Carats - Carats
  • Colour - Colour
  • Clarity - Clarity
  • Cutting - Cutting quality

The 4Cs not only provide verifiable information about the quality of your stone, but also make it possible to trace your diamond. When you go to buy diamonds, you will always get a certificate that proves the value of your diamond.

How can I protect my gold and diamonds?

How can I clean my jewellery myself?

What are the other options?

Your timeless gold jewellery set with diamonds adds the finishing touch to any dress and radiates pure luxury. As long as they shine, they retain their special, classy appearance. But what if my jewellery has become a little dull and unshiny?  What if they start to lose their original shine? With the following advice from Diamante Sicuro, your jewellery will stay as good as new!

How can I protect my gold and diamonds?

The protection of your jewellery starts with how you keep it. Surely you won't wear your white gold earrings with diamonds every day and where do you keep them when you don't wear them? It is best to keep your diamond jewellery separate. Because diamonds are the hardest precious stones in the world, a diamond can only be damaged by another diamond. To make sure they don't scratch, you should keep them in their original box, in a soft case or in a specially designed jewellery box. In this way automatically protect your precious jewellery with rubies, sapphires, emeralds or other precious stones.

When they are not stored, you must wear them with care. It is best to put your jewellery aside when swimming, showering, sleeping, gardening or working out. Also be careful to touch your diamond as little as possible. Oils and dirt on the skin can transfer to the diamond and cause it to become dull.

How can I clean my jewellery myself?

You can easily clean your jewellery without running the risk of damaging it. Maybe it's easier than you think: gold, platinum, diamonds and precious stones can be cleaned with warm water and soap or ammonia.

How can I clean my gold and diamond jewellery with lukewarm water and soap?

Immerse your jewellery in a bowl of lukewarm water, mixed with detergent and cooking salt or soda. Polish it with a soft toothbrush and rinse it with lukewarm running water. Dry the jewel with a soft, fibre-free cloth. Do not use paper towels, as they may scratch your jewellery.

How do I clean my jewellery with ammonia?

Put your jewellery in a bowl containing 3 parts warm water and 1 part ammonia. Let it soak for half an hour and polish your jewellery with a soft toothbrush. Rinse with clear water and let it dry.

Be careful especially with white gold jewellery. White gold is obtained by mixing gold with other materials to form an alloy. On this, a layer of rhodium is applied to give your white gold ring a brilliant sparkle. If you rub it too hard, the rhodium layer could be damaged.

What are the other options?

What if I prefer not to clean the gold and diamonds myself or if I don't have the time? You can always choose to have your jewellery cleaned professionally. Jewellers can use an ultrasonic cleaner to give your jewellery that perfect cleanliness. This small machine removes impurities from the smallest corners using vibrations. It is ideal for cleaning intricate jewellery, as it removes dirt from places that a toothbrush cannot reach.

As soon as we receive your payment, we will start the production process of your jewellery.

Since our jewellery is handmade, it can be finished in more detail and we can achieve a higher quality, unlike mass produced jewellery.

Buying jewellery online from Diamante Sicuro means buying jewellery made with the most durable and certified materials. Your gold, platinum and diamond jewellery is always of the highest quality and retains its shine in an exceptional way.

Which gold uses Diamante Sicuro?

Our gold is always 18 carats, regardless of whether you opt for white, yellow or red gold. This means that the alloy is 75% pure gold, mixed with silver or copper. When you decide to buy jewellery online from Diamante Sicuro, you can be sure that you have the highest possible standard. After all, a higher grade of pure gold would make your jewellery too weak. Of course we do not use alloys that cause irritation.

Which platinum does Diamante Sicuro use?

Some brands say that their jewellery is platinum when it contains only 50% platinum. Diamante Sicuro always uses 95% certified pure platinum, mixed with ruthenium. Our platinum also has a higher melting point, which complicates the production process but increases its durability.

Your platinum jewellery cannot therefore lose its metallic sheen and perfect white colour over time.

What is a content stamp?

A content stamp is a quality mark that protects the consumer from fraud and the jeweller from unfair competition. By including a content stamp in our jewellery, you can be sure of the quantity and quality of the precious metals used in the alloy when you buy jewellery online. The content stamps used are:

"au750" for gold: 18K gold only (= 75% gold)

"pt950" for platinum: 950 platinum only (= 95% platinum)

The city of Antwerp, where Diamante Sicuro is located, has been renowned since 1447 as a world quality centre for the diamond trade. Today Antwerp owns more than 50% of the shares of the diamond trade worldwide.

For over 70 years, the people behind Diamante Sicuro have been directly selecting the highest quality diamonds and the largest diamond resources available in the world. Intermediaries are avoided in this process of direct buying and selling, combining this with efficient stock management, which allows Diamante Sicuro to offer a better and wider choice at the best value for money. Diamonds are purchased directly at source from Diamante Sicuro and you can buy these high quality diamond jewellery online or by appointment in the Diamante Sicuro showroom.

Diamante Sicuro is building a rapidly growing customer base around the world in a cost efficient way, as more than 90% of its customers buy online (through our 2 language E-boutique, where customers can pay in different currencies and through a wide range of payment methods). All this without investing in luxury retail outlets and the associated overheads. This gives Diamante Sicuro the opportunity to offer diamond jewellery at an exceptional price and quality to its customers who choose to visit the showroom in Alcamo (TP) - Italy.

At Diamante Sicuro, there is a commitment to customers to underline the strong link that exists between the prices of the products offered with the intrinsic cost of the underlying components and the materials used for the jewellery.

What does the colour of the diamond mean in colourless diamonds?

What are impurities in diamonds?

How do you recognise good cutting quality?

What combination gives the highest quality?

When buying diamonds, there are some decisive elements. In particular colour, purity and cutting quality are of paramount importance. But how do I recognise the right values? With Diamante Sicuro you opt for the highest quality at the best possible price.

What does colour mean for colourless diamonds?

Colour is also an important factor for colourless diamonds. Lower grade colours have a visibly yellowish tint, while very high grade colours become quite expensive due to their rarity.

Diamante Sicuro offers these high quality colours on request, but our collection of almost colourless diamonds contains only F to H colours. F is the highest. The very light colour is only visible to the naked eye if you compare the stone with higher quality diamonds.

With an H grade diamond, the colour is slightly visible to the naked eye.

What are impurities in diamonds?

Apart from colour, purity is a second important aspect. During the entire diamond formation process, the stones take on small cravings. When these are inside the diamond, they are called impurities. On the outside, they are called defects.

From Diamante Sicuro, you can buy standard diamonds with a VS or SI level of purity. VS diamonds contain inclusions that are not recognisable to the naked eye. With SI diamonds, inclusions may be slightly distinguishable, but only in very good condition.

Lower quality diamonds have visible imperfections; higher quality diamonds are rarer. Diamonds with a different level of purity can be ordered on request.

How do you recognise good quality cut diamonds?

Colour and purity are important properties for diamonds, but the most important thing is probably the cutting method. The typical sparkle and sparkle of a diamond can only be recognised if the cutting process is done well.

The quality of the cut is measured by size, symmetry and lustre. It is the only human factor that plays a role. If the diamond is not deep enough or is too deep, light comes out along the sides or the bottom of the diamond. A well-cut diamond will let light pass through the crown.

Diamante Sicuro also offers diamonds with the Very Good Cut label. Approximately 15% of diamonds offered worldwide receive this label. They reflect almost the same light as diamonds with an ideal cut, but their price is lower.

What combination gives the highest quality?

We offer two quality combinations, both of which guarantee a diamond with a beautiful white colour and high purity: G-VS and H-SI. Thanks to the optimal cut quality, all our diamonds have a truly wonderful brilliance. The G-VS combination shines just a little more than H-SI, thanks to the small difference in colour and purity. This difference is only visible when you compare diamonds next to each other.

What other factors are important for diamonds? How do I know for sure that I have the right diamond? Ask the diamond experts at Diamante Sicuro for advice on the right choice.

Diamante Sicuro offers a variety of ring models to suit all tastes and styles.

      1. Solitaire ring

Solitaire rings are the most popular choice for diamond engagement rings and for good reason. By putting a single diamond in the centre of a ring, it will be the centre of attention.

The most common setting for a solitaire ring is the classic 6-pointed ring. This setting has six tines, also called claws, which hold the diamond firmly in place. Holding the diamond in this way, instead of setting it in the band, leaves more space, which means more brilliance.

This traditional setting is obviously not the only option for engagement rings; there are other possibilities for solitaire rings and also for completely different ring models.

      2. Solitaire with side diamonds

When there are small diamonds set on the ring band of a solitaire ring. The small diamonds on the band of the ring accentuate the brilliance of the central diamond. It enhances the focus of the big diamond and makes it look even bigger.

      3. Eternity ring

With an eternity ring, many small diamonds cover the entire surface of a jewel. The diamonds are set next to each other so that you can't see the metal and only diamonds are visible, which is really breathtaking, because all you can see are rows of brilliant diamonds with no visible space between them.

      4. Trilogy ring

A trilogy ring is a ring set with 3 diamonds, and stands for "past, present and future".

If you choose 3 diamonds, the best option is to have a larger centre diamond to attract all the attention and let it be assisted by two smaller diamonds.

      5. Toi et Moi

Toi et Moi means "You and I" in French and refers to a ring with two diamonds. This design represents the interweaving of two souls and was therefore very often given as an engagement ring. The two stones can also represent two hearts eternally united, which is proof of an "indestructible" couple.

The proximity of both stones and the fact that they are of the same shape and size suggests balance and fairness.

      6. Aureola

A diamond halo ring is a ring with smaller diamonds surrounding the central stone. The term "halo" is used because the central stone appears to have a halo. The main advantage of a halo design is that it makes the central stone or diamond look bigger.

The shape of the gemstone can range from a round cut, cushion cut, pear cut, or other shapes.

All the above designs can be found on our website. Should you wish to create a custom design, please do not hesitate to contact our experts (info@diamante-sicuro.com) for more information.

The very first diamond jewellery e-commerce sites were launched about ten years ago. Today, there are many diamond jewellery e-commerce businesses, which together constitute the fastest growing category in the industry. Blue Nile - the pioneer (www.bluenile.com) - alone generates around $300 million a year. Depending on the sources, the worldwide jewellery e-commerce turnover reaches around $4-5 billion (out of a total of $75-80 billion). For example, in 2009 (a very difficult economic year) the sub-segment of e-commerce jewellery sales grew, and also grew quite significantly more than other e-commerce sectors, thanks to the upward movement of the diamond jewellery industry. This trend is also occurring in all important consumer markets (Europe, Middle East, Japan, Russia, China, India and Brazil).

This trend has been confirmed in the last two years, and all studies predict further growth in the jewellery e-commerce industry, compared to classic jewellers (such as Cartier, Tiffany & Co, Boucheron, De Beers, Van Cleef & Arpels, Chopard, Piaget, Bulgari, ...). It is essential to know that this trend persists in Europe, as several American sites (www.jamesallen.com, www.ice.com, www.bluenile.com, www.thediamondstore.co.uk,...) are also gravitating towards the European continent, and many European diamond jewellery e-shops are being set up.

At the moment, Diamante Sicuro is one of the very few online diamond jewellery brands that, well considered, offers all its diamond jewellery and collections (at its multilingual e-boutique www.diamante-sicuro.com) without intermediaries or retail outlets (with the exception of our showroom in Alcamo (TP) - Italy).

A hallmark protects you from fraud and protects traders from unfair competition. Gold and silver have been mixed with other metals for centuries, as they are too soft in their original form to make jewellery. It is not possible to recognise at a glance the amount of cheaper metals used during manufacture. A gold layer of a couple of microns may look like real gold when it is still new. Most jewellers and skilled chemists cannot tell how much of the noble metal is present in an alloy.

Because of the high price of noble metals, some rogue merchants are tempted to use less precious alloys. This fraud is difficult to detect, and honest traders and customers are deceived.

There has always been a need to protect the public and suppliers. For this reason all items sold as gold, silver or platinum must be marked with a mark confirming their compliance with the law. This way you can, for example, see what percentage of gold your white gold jewellery has when looking at the mark.

In addition to the standard jewellery listed on diamante-sicuro.com, we also offer a tailor-made service, so we guarantee unbeatable prices for our high quality diamond jewellery.

In case you have seen a specific design on our website, but would like to change the size of the diamond or diamonds, the quality of the diamond or diamonds (higher than the standard quality listed on our website), or would like to change the diamonds into gems (rubies, emeralds, sapphires, etc.), you can contact us by email to receive a personal quote.

When you contact us for a quote, please quote the following information:

  • Specific design you have seen on our website
  • Diamond/gemma size
  • Diamond/gemma quality
  • Any other changes you would like to make
  • Estimate your budget

If you want to change the shape of the diamond(s), this is also possible, but in this way we will also have to change the design of the jewel.

If you would like to receive a quote for a tailor-made jewel, please do not hesitate to contact our experts, we will be happy to assist you.

Secure diamond can engrave a name, date or short message on most of its jewellery. Contact our diamond jewellery consultant at info@diamante-sicuro.com or call +32 493 42 5875 / +39 324 2697167 (also whatsapp) for more information.

Each Diamante Sicuro jewel comes with an exquisite gift box of jewellery, which includes the Diamante Sicuro jewellery box.  This box protects the jewellery during transport and is perfectly suitable for a gift.

In line with our diamond jewellery, Diamante Sicuro uses only high quality materials for packaging. In addition, each Diamante Sicuro jewellery box has a black velvet lining and an elegant coating.

If you are interested in a jewel that is temporarily unavailable, please contact us at info@diamante-sicuro.com or dial +32 493 42 5875 / +39 324 2697167 (also whatsapp) and ask our diamond jewellery consultants.

The tennis bracelet is a very popular piece of jewellery and has a fixed place in the jewellery box for many women. This jewel exudes elegance through the refined bracelet set with small white diamonds. Simplicity in itself! The tennis bracelet is named after tennis. And if you follow tennis, you may already know this story. In 1987, the best American tennis player Chris Evert played at the US Open. Evert always wore a diamond bracelet on the tennis court, designed by George Bedewi. Journalists therefore often referred to his jewellery as a "tennis bracelet".

The diamond necklace is the widest canvas of a jewellery designer. It is a means to express both the sublime and the beautiful. The charm of our diamonds, in the hands of the world's most skilled craftsmen, produces jewellery of exceptional quality and meaning.

Over time, pendants and diamonds have had a special meaning for different cultures. Diamond pendants are worn not only for their ornamental value, but also to express the identity and social status of the wearer. Diamond pendants have also been associated with mysterious powers of protection.

Diamond earrings are the perfect gift for your girlfriend, wife or girlfriend. Every woman wants a pair. Diamond earrings are probably the most versatile jewellery there is. They can be worn with anything and on any occasion. Diamond earrings can be worn for casual evenings, but are also suitable for work and formal occasions.

Diamond earrings are a magnificent variety of diamond earrings. Also with precious metal you have a wide range of options, with earrings in white gold, yellow gold, red gold and platinum. Some earrings for women, such as diamond studs, have seen great changes and are now suitable for both sexes.

You will receive a diamond certificate for each stone. It is a document protected by a laminate that summarises the vital information of a diamond and describes precisely the characteristics that contribute to its value. A certificate gives no indication of the monetary value of a diamond.

Diamante Sicuro deliberately chooses never to offer inferior qualities. And this in a highly transparent and objective way. For this reason Diamante Sicuro only cooperates with the most renowned certificates of the diamond industry worldwide: GIA, HRD and IGI.

GIA: Gemological Institute of America

HRD: High Diamond Council - Hoge Raad voor Diamant

IGI: International Institute of Gemmology

Diamante Sicuro therefore explicitly dissociates itself from practices such as self-written diamond certificates (a practice that apparently still exists a lot) and lower quality certificates from less reliable laboratories. In this way we protect our customers from the risk that the diamond (jewel) will be of inferior quality (and value) at a future resale (and possible recertification by GIA, HRD or IGI).

Finally, we would like to underline the fact that Diamante Sicuro does not show the certificates in advance, which is one of the reasons why you can enjoy an extremely competitive price. In this way, Diamante Sicuro does not need to invest in an expensive and inefficient stock or is limited to diamonds that can be reserved (which are always supplied at an additional price, without offering any real added value).

Therefore, after receiving payment, Diamante Sicuro purchases the most beautiful diamonds at source, in complete freedom and without any restrictions, completely in line with the promised quality standards, which are communicated very clearly and transparently in the description of the diamond jewel purchased. This explains the unbeatable quality/price ratio you enjoy.

The WTOCD (Scientific and Technical Research Centre for Diamonds) developed the distinctive Hearts & Arrows brand of HRD Antwerp in 2009. The criteria of objectivity and an automatic system of experts developed specifically for verifying whether a diamond meets the Hearts & Arrows criteria are used. Further information can be found on their website. The Hearts and Arrows model refers to a symmetrical light model visible using a special diamond-cut viewer within certain narrow specifications.

The brilliant cut diamond has 57 facets. When all these facets are in harmony, the result is a repeatable and almost perfect pattern of eight symmetrical arrows when the diamond is seen from above and eight symmetrical hearts when the diamond is seen from below.

Diamond experts do not agree which diamonds should receive the "Hearts and arrows" label. This is because there is no industry standard, so one person or company may label a diamond as "Hearts and Arrows", while another may disagree. In the diamond industry, the term "super ideal" is a common term used to describe diamonds that have perfect optical symmetry. Most diamonds with an overall cut classified by the GIA as '3 x eccellent' (with excellent cut, symmetry and polish) or by the American Gem Society as '0' (or 'ideal') will have a kind of hearts and arrows pattern when seen through an H&A viewer, but the pattern may not be perfect. Most diamond experts believe that the hearts and arrows model should be graded, and only those with the highest grade should be called hearts and arrows. These people also believe that the Hearts and Arrows model alone is not sufficient to be considered a Hearts and Arrows diamond; the model must be perfect to fit certain guidelines.

Often the presence of the Hearts and Arrows pattern is taken as confirmation that the diamond is well cut. This is not necessarily true. In a round diamond, a well-defined set of 8 hearts and 8 arrows is a sign of excellent optical symmetry, an important component of the cut. As such, its appearance is most likely a superior cut sign, but not a guarantee.

The IGI and HRD laboratories classify hearts and arrows as "optimal cut". IGI also has a specific certificate. GIA does not recognise Hearts & Arrows as a component of the cut grade, this part due to the fact that the presence of the model is not a guarantee of the cut. But, GIA certificates sometimes contain a note with the words "Laser registration: H&A". This note on the GIA certificate simply indicates that "H&A" was laser engraved on the diamond belt before it was classified by GIA. Neither the laser inscription "H&A" nor the corresponding note on the GIA certificate indicate that the GIA observed the Hearts and Arrows model on the specific diamond.

The diamond industry has not established precise criteria for the assessment of diamonds on Hearts & Arrows. For consumers wishing to purchase diamonds of this specification and cut quality, it is best to review the Hearts and Arrows images under an H&A viewer.

Our experienced Safe Diamond experts can answer any additional questions you may have and, if you wish, search for diamonds on your behalf that match your criteria.

A fake diamond is heavier than the real one when it is the same size. Furthermore, a fake diamond does not have the same brilliance as a real diamond. Over time, it becomes more opaque, unlike a real diamond, which never loses its brilliance.

The atomisation test is also a useful method of distinguishing real diamonds. A fake does not immediately repel heat, unlike the real one.

As a service to our customers, we can also use a diamond tester at our Diamante Sicuro showroom to check if the stone is really a diamond.

Diamonds are available in different shapes. Each shape has different and unique characteristics that determine its specific quality. In most cases, Diamante Sicuro uses the following four forms of diamonds for its jewellery:


The round brilliant cut diamond is by far the most popular and sought after diamond shape available today. This shape has set the traditional standard for all diamond shapes. In addition, a round diamond will generally give you more flexibility in terms of balance of cut, colour, and degrees of clarity, while still getting the fire and brilliance you want and is the most classic choice. White gold earrings with a round diamond, for example, are extremely versatile.


The princess diamond has a square shape, with a length/width ratio of about 1.00 and 1.05. The princess cut is also called the square modified brilliant cut, square cut or rectangular modified brilliant cut. The latter term is used when the proportions exceed 1.05. The cut requires more weight to be directed towards the depth of the diamond in order to maximise brilliance. Depth percentages of 70% to 78% are not uncommon with these diamond shapes.


This brilliant-cut diamond looks like a glittering drop because of its unique tip and rounded end. The unique appearance of the pear diamond makes it a popular choice for a variety of jewellery such as diamond pendants and diamond earrings.


The oval diamond has a traditional cut shape with a special touch. This shape is slightly less common than a brilliant and yet it comes close to the sparkling brilliance of a brilliant-cut diamond. This diamond cut is popular among people with small hands and thin fingers because the elegant oval shape has an elongating effect. Oval diamonds are also often seen in the engagement rings of European celebrities and princesses.

On request, Diamante Sicuro also offers other forms of diamonds such as heart, emerald, marquise, rodiant or pillow.

What does the term "brilliant" mean?

How does it affect the quality of my diamond?

Why should I buy a brilliant and not another diamond cut?

The terms "brilliant" and "diamond" are often used interchangeably. However, they are not synonymous. "Diamond" is the name of the precious stone itself, while "brilliant" denotes the cut of a diamond. But why are they so often confused? And why should I buy a brilliant instead of another diamond cut?

What does the term "brilliant" mean?

The term "brilliant" is actually an abbreviation of "brilliant cut"; a method of cutting a diamond that optimises its appearance and the way it reflects light. The term "cut" can refer to both the shape and the cutting quality of a diamond. The latter is one of the 4 C's, designed to describe the quality of diamonds. A well cut diamond has a higher reflection. A brilliant cut diamond, with the ideal number of 57 facets, therefore has a more intense brilliance and greater charm.

Of all diamond shapes, the brilliant cut is the most brilliant. For this reason, this diamond shape is highly sought after for engagement rings, a classic white gold ring with a brilliant or delicate brilliant earring.

How does it influence the quality of my diamond?

The quality of a diamond's cut refers to its proportions, symmetry and lustre and is therefore one of the most important characteristics of a diamond. If its depth is too deep or too shallow, the light entering the diamond through its crown comes out instead of being reflected.

Diamond shapes other than the standard round cut are called "fancy shapes". The best known shapes are marquise, pear, oval, heart and emerald.

Why should I buy a brilliant and not another diamond cut?

Each diamond cut has its own unique characteristics. A daisy cut, for example, is one of 6 ways to make your diamond look bigger. After all, bigger diamonds have a higher price. Others opt for a fancy cut instead of the classic brilliant because it adds a more original and personal touch to their ring.

The brilliant can now be more original than it was in the past, for example with an uncommon setting. A wedding ring with a diamond is an alternative, while the classic choice would be a smooth wedding ring.

Natural fancy diamonds are very exclusive and rare, even rarer than colourless diamonds. A true natural coloured diamond has been given to us by nature and can be found in a variety of colours, from pink to yellow, brown and even red. Coloured diamonds are only found in very limited areas.

Only one diamond in 10,000 has a natural colour and is therefore called a fancy diamond. Fancy diamonds are purchased almost exclusively for the intensity and colour distribution of the diamond. The criteria considered when buying a white or colourless diamond, such as cut proportions and purity, are less important when buying a fancy colour diamond.

Why is diamond a stable investment?

What is the difference with diamond jewellery?

What is the added value of diamonds and diamond jewellery Safe Diamond?

Diamond prices are stable for long periods of time. But what happens if I look at the price of diamonds over a period of 100 years? You will notice that it has increased steadily due to the value of the index. This means that diamonds are generally a very stable investment. We say "in general" because there are exceptions for certain categories and certain periods over time. Diamante Sicuro explains the influencing factors.

Why are diamonds a stable investment?

Recent indicators and studies predict an increase in the price of diamonds over the next few decades. The price of a diamond is mainly determined by its quality and type. The price of a coloured natural diamond, for example, has risen over certain periods of time, especially compared to colourless diamonds. Some categories of polished diamonds, on the other hand, may decline in value due to a temporary surplus. If large mining companies anticipate a drop in sales, they will anticipate it by reducing the volume of diamonds they bring to the surface or avoiding the more difficult places to mine.

The effect in the medium-term future is a substantial drop in supply, causing small deficits in the diamond market and an increase in prices. In other words: a good investment.

What is the difference with diamond jewellery?

The value of diamond jewellery is something completely different. Due to additional factors such as currencies, craftsmanship and commodity prices, the value is more difficult to speculate on. They are also more stable, however, because of the importance of work and design. Diamond jewellery of a certain high quality brand is often considered more special because the guarantees of that brand also have an influence.  Not only the diamond and precious metal is paid for, but also the craftsmanship and reputation of the brand.

What is the added value of diamonds and diamond jewellery with Diamante Sicuro diamonds?

Diamante Sicuro has chosen to differentiate itself from other brands. Not in terms of quality and design, but rather in terms of innovation in terms of purchasing, stock management, distribution and marketing. Diamante Sicuro only invests in what makes the whole process more efficient, with the result of obtaining a correct price for your diamond. As more than 90% of our customers buy our jewellery online, we are able to build a rapidly growing customer base around the world in a very cost-effective way.

What should I pay attention to when buying diamonds?

What to choose: diamond jewellery or loose diamonds?

What should my investment budget be?

What is a smart way to diversify my investment portfolio? Resources are always a good idea, especially when they have an intrinsic value such as diamonds. Whether you buy loose diamonds or diamonds set in jewellery, Diamante Sicuro is here to help.

What should I pay attention to when buying diamonds?

Carats: Diamonds from 1.00 ct. to 6.00 ct. are ideal for resale. 3 diamonds of 3.00 ct. each are generally a more interesting investment than a single 9.00 ct. diamond.

Purity: higher than VS and up to IF.

Colour: white diamonds must have a colour grade D, E or F; coloured diamonds must be intense.

What to choose: diamond jewellery or loose diamonds?

Whatever you are looking for, at Diamante Sicuro you will surely find diamonds with the best quality/price ratio. The craftsmanship and aesthetics are more evident with jewellery. For an investment, however, the focus is mainly on a higher quality diamond.

Thus, with loose diamonds, we aim for rarer diamond characteristics, while for diamonds set in jewellery it is sufficient to be a beautiful white with visible impurities. With jewellery, on the other hand, we also add the value of precious metal such as platinum, yellow, red or white gold.

What should my investment budget be?

You can start investing in a rare and precious resource like diamonds with a budget of € 5,000 - € 6,000, for a single diamond of 1.00 ct.

Diamonds are precious, rare, mysterious, beautiful, magical and romantic symbols of love. Diamonds are mostly considered a safe investment, but in addition to this, they also give a feeling of beauty, luxury, belonging, passion and love. No other financial investment can offer you so much!

In difficult times, a recommendable investment mix is what you can do:

1/3 of real estate

1/3 fixed-rate securities

1/3 movables/raw materials, such as diamonds

Diamonds are particularly suitable as movable goods because they bring some essential advantages:

Protection against inflation, market collapse, currency reforms

Anonymity (no registration required)


Worldwide convertibility, which means that diamonds are - along with gold - the only internationally accepted alternative currency that retains the same value worldwide

No value added tax (= tax-free improvement)

Almost no maintenance costs

Very prestigious

Price independence - prices are independent of government laws and therefore diamonds retain their value better even during the recession.

Robust price performance - historically, diamonds have recovered well from the collapses in prices and the economy.

Not to be forgotten: diamonds have an important emotional value that lasts for several generations.

Theoretically a (world) war could devalue any currency, real estate can lose its value, new technologies can replace resources, competition can ruin companies, but nothing can systematically undermine the long-term value of diamonds. Over time, diamonds will become increasingly rare, just like any natural resource. This fact has the fundamental multiplier effect on the long-term value of diamonds.

Diamonds are - along with quality works of art - one of the very few assets that combine its practical use with the investment aspect. That is, while you can wear your diamonds set in/as jewellery, they also symbolise your most secure investments.

Strong supply and demand - the expected widening of the imbalance between supply and demand is at the root of the price with a strong possibility of accelerating prices

Finally, while most other luxury goods, such as cars, furniture, furs, etc. lose their value over time, this is not the case with diamonds, precisely because of their durable/ indestructible nature.


When investing for very high or speculative returns, one should not invest in diamonds.

If you want a very secure investment that maintains and strengthens its underlying value, and that you can convert at any time, diamonds are best for you.

"Diamond" comes from the Greek word adamao, which means "domesticated" or "submissive". Since ancient times, the adjective adamas was used to describe the hardest substance known to man. Eventually it became a synonym for the word diamond. It is believed that adamas previously referred to the second hardest mineral, corundum (the variety of gems is sapphire).

The origin of the diamond, as well as its multiple connotations, can be found in India, where it was first extracted. The word most used in Sanskrit to indicate the diamond is vajra, "lightning" and indrayudha or "Indra's weapon". Since Indra is the warrior god of the Vedic scriptures (the foundation of Hinduism), the symbol of lightning says a lot about the Indian conception of diamonds. The lightning bolt recalls the light reflected from a fine diamond octahedron and its indomitable hardness).

Conflict diamonds are diamonds that come from conflict areas, where local militias try to use diamonds to finance their activities. The Kimberley Process Certification System was established to prevent these diamonds from entering the world market by controlling the origin of conflict diamonds from conflict zones.

The Kimberley Process is an international system that regulates the diamond business to ensure that diamonds come from conflict zones. The Kimberley Certificate guarantees that your diamond is not a conflict-free diamond. It has been established that, since 2008, 99.9% of diamond transactions have involved non-conflict diamonds.

Obviously Diamante Sicuro has a zero tolerance policy towards diamonds from conflict zones. We only purchase diamonds through the most respected diamond producers who act in line with the standards set by the Kimberley Process.

What route do diamonds travel?

Where are they extracted most often?

Where does the importance of a diamond engagement ring come from?

The mysterious nature of diamonds should not mean that their origin should also remain a secret. Around 80% of all rough diamonds in the world pass through Antwerp. But where do they come from? And how did the tradition of adding diamonds to an engagement ring come about?

What route do diamonds travel?

Diamonds still have a long way to go before they can shine in your jewellery. To extract 1 carat, or 0.2 grams, of diamond, you need to remove about 250 tons of earth.

Where are they extracted most often?

Did you know that the origin of diamonds is in India? Now they are mined all over the world, in large mines in Australia, Africa and Canada, among others. Although mining used to be very profitable, many diamond mines have started to dry up in recent years. For this reason, the diamond industry is studying other options, such as diamond mining in Antarctica or underwater mining. However, the real diamond trade will not see many differences. Rough diamonds will inevitably end up in Antwerp.

Rough diamonds arriving in Antwerp are without exception extracted and traded in an ethically responsible manner. This is possible thanks to the Kimberley International Process.

Where does the importance of a diamond engagement ring come from?

Since 1948, almost all brides have wanted a diamond ring. For this we have to thank De Beers' famous marketing campaign "Diamonds are a girl's best friend". This company is still the market leader when it comes to diamond mining, with direct involvement in over 19 mining activities. It produces about half the world's supply of diamonds. There is therefore a very high probability that your diamond will come from one of these mines.

Would you like to know more about the diamonds that Diamante Sicuro uses in its jewellery? Or do you have some other question? Ask the Diamond Sicuro diamond experts for advice and find out everything you want to know.

In the 13th century, an act of St Louis (Louis IX of France, 1214-70) established a law of sumptuousness that reserved diamonds for the king on the basis of their rarity and the value they were given at the time. From that moment on, diamonds began to appear in royal jewellery for both men and women. From the 17th century onwards, they were also seen with the greatest European aristocracy and the class of wealthy merchants.

It is believed that the first diamond cutting industry was located in Venice (Italy) around 1330. It is estimated that diamond cutting found its way in Paris and Bruges towards the end of the 14th century and later in Antwerp.

In 1499, the Portuguese navigator Vasco da Gama discovered the sea route to the East around the Cape of Good Hope, providing Europeans with a final route around the Arab impediment to the trade in diamonds from India. Goa, on the Malabar coast in India, was created as a Portuguese trade centre and a diamond route from Goa to Lisbon to Antwerp was developed.

Diamonds are used in many exquisite jewellery pieces and are available in various sizes. But it is in its smallest form that most captures our interest: the diamond ring given as a sign of love and marriage. The current history of this tradition transcends the perception of its creation as a marketing hyperbole. The modern solitaire is only the most recent step on a long road of the past.

The rings date back several millennia, but those given as a sign of love are first remembered by the Roman comic poet Plautus in the 2nd century BC. At that time, wedding rings were known for the internal inscriptions that recorded marriage contracts signed in the presence of the image of the emperor. This custom was carried on and Christianised in the 4th century, when priests no longer allowed weddings without the exchange of faiths.

Diamonds go a long way before they are set in your beautiful jewellery. The mine is the first step, but what comes next? Not all roads leading to your collection are the same, and the road to Diamante Sicuro is the most exceptional. Discover the journey of your diamond.

  • Extracting diamonds from the mines
  • The obvious route
  • The unusual route

Extracting diamonds from the mines

The journey of a diamond begins in a mine somewhere in Australia, India, South Africa or Canada. There, rough diamonds are mined in kimberlite quarries. Once this is done, the rough crystals are sorted according to size, colour, shape and other chemical and physical characteristics. From this point, there are two possible routes from the diamond mine to traders such as Diamante Sicuro.

The obvious route

The most obvious and safest way for you consumers is through the channels of De Beers, the world's largest mining group, or one of its competitors such as Australian Rio Tinto or Botswana Debswana. De Beers is probably also the best known mining company for its advertising and its famous motto: "A diamond is forever".

The mining companies organise sales sessions ("sights") where diamonds, which have not been processed since they were mined, can be purchased by diamond craftsmen. These are exclusive events, by invitation only. Guests can choose to buy the diamonds themselves or sell them to smaller traders.

Smaller traders cut the rough diamonds and sell the polished gems to jewellery makers or diamond wholesalers. Jewellery makers then put them into finished jewellery and sell them to jewellers. Wholesalers in turn sell them to diamond retailers.

The unusual route

The other way is much less obvious and much less used. Independent miners can choose not to sell their assets to a mining group like De Beers. This is not very common because most mines are managed by a mining group. Mine workers will then sell the proceeds from the diamond mine directly to other buyers. These buyers can in turn choose to cut the diamonds and try to sell them to themselves, or they can resume the process as in the obvious route.

As diamonds are generally increasingly bought and sold online, they have also found their way on the Internet. Diamante Sicuro makes it easier to buy jewellery online at competitive prices. In addition, Diamante Sicuro is a fervent supporter of the Kimberley Process. This international partnership bans conflict diamonds from the international diamond trade.

How did the diamond get to Antwerp?

How did Antwerp regain its position?

What does the current Antwerp diamond market look like?

People all over the world know that Antwerp is the right place for people looking for a diamond. The city has raised the profession of diamond cutting to a higher level and has developed a unique experience and a reputation for cast iron over the centuries. But how did the diamond get to Antwerp? How did we maintain this position?

How did the diamond get to Antwerp?

Antwerp has been a strong diamond production centre since the 16th century. The modern diamond cutting was invented by a resident of Bruges in the middle of the 15th century and the techniques were perfected by Kempen cutters. Bruges' reduced port activity shifted the global diamond import to Antwerp and the diamond industry flourished in its new port city. However, this vibrant new diamond city was short-lived. The northern Netherlands separated from the southern Netherlands at the end of the 16th century, after which the diamond traders of London and Amsterdam ruled the port.

How did Antwerp regain its position?

Antwerp did not regain its position at the top of the diamond industry until the beginning of the 20th century. Although the city was not at all at the top, the diamond industry continued to exist in Antwerp. Cutters perfected their craftsmanship and the market remained small, but they actively kept up with the times. After the Second World War, the elite were able to easily buy back diamonds, thanks to well-organised import and export in Antwerp, no matter where they came from.

What does the current Antwerp diamond market look like?

The city began to grow significantly again at the beginning of the 20th century and did not stop there. Today about 80% of the world's rough diamonds pass through Antwerp. Moreover, the quality of diamond cutting in Antwerp is renowned all over the world. Not only in the diamond industry, as Antwerp has managed to maintain its excellent reputation by offering the same quality while constantly innovating. This means that you cannot only buy diamonds in Antwerp from a physical jeweller, but nowadays there are also countless possibilities to buy your jewellery online. Antwerp: the city of diamonds, and rightly so.

Where exactly is the diamond district located?

Why is the diamond district in Antwerp worth visiting?

How was the diamond district born?

You have certainly heard a lot about Antwerp's diamond district, also known as the Diamond Quarter. The place is known throughout the world for its important role in the diamond trade. Diamond traders cut, polish and sell diamonds, and jewelers assemble them into jewellery. What is so special about the Diamond District?

Where exactly is the diamond district located?

The Antwerp Diamond District, or the Diamond Quarter, is perhaps the best place in the world for people looking for diamonds. Antwerp is known throughout the world as the diamond city par excellence. But this epicentre is only 1 km2 in size. It consists of five roads, three of which are traffic-free. De Rijfstraat, Hoveniersstraat and Schupstraat are the heart of the district. The diamond merchants of the Vestingstraat and Lange Herentalsstraat focus more on tourists looking for diamonds.

Antwerp's diamond district is also easy to reach from abroad, as it is located right next to Antwerp Central Station.

Why is the Antwerp Diamond District worth visiting?

A visit to the diamond district is a must, not only if you really want to buy diamonds. Of course there are many beautiful jewellery and loose diamonds, but the architecture and other attractions in the district are also interesting.

There is the Diamond Exchange (Beurs voor Diamanthandel) in the Hoveniersstraat, formerly known as the Antwerp Casino. In addition, there is the Office of Diamonds, where all diamond imports and exports to Antwerp are registered. It is part of the Antwerp World Diamond Centre (AWDC), the central organisation of the diamond industry, founded in 1973.

Those interested in the Jewish faith can also enjoy themselves. The Portuguese synagogue is located in the centre of Antwerp's diamond district. The building resembles a neo-Romanesque church, but its austerity distinguishes it from the large office buildings in the district.

The DIVA diamond museum and the MAS diamond pavilion are located outside the diamond district, but are well worth a visit. There you will learn more about the history of trade, industry and the diamond district.

How was the diamond district born?

During the 16th century, Antwerp began to profile itself more and more as a trading city, thanks to its lively port. Diamonds were initially shipped from India to Bruges via Venice, but after the decline of the port of Bruges, Antwerp became a leader in the diamond trade.

Originally, the area around Groenplaats was the diamond district, but it moved several times over the centuries, including to Paardenmarkt and Meir. Since the beginning of the 20th century, the diamond district has been firmly established in its position near the Central Station. Since the 1970s, the economic importance of the diamond trade has increased for the city of Antwerp, and exchanges and auction houses have been established.

You can't talk about diamonds without talking about De Beers, the company that alone has made the diamond industry what it is today. De Beers was founded by Cecil Rhodes, who also founded the state of Rhodesia, which later became Zambia and Zimbabwe. The Rhodes Scholarship is also named after him and is funded by his assets.

Rhodes began by renting water pumps to miners during a diamond rush in 1867 in Kimberley, South Africa. He expanded into mines and about twenty years later became the sole owner of all diamond mining operations in the country.

Rhodes has incorporated De Beers into a diamond group. De Beers mines diamonds, then manages their sale and distribution through various entities (today it is known as the Diamond Trading Company, whereas before it was simply called "the syndicate" and the CSO or Central Selling Organization).

If you want to buy diamonds from De Beers, you have to play by their rules: diamonds are sold at events known as "sights". There are 10 attractions each year, and to buy, you have to be a sight holder (these are usually diamond dealers whose business is to have the stones cut and polished and then resell them at diamond sorting centres in Antwerp, New York and Tel Aviv).

Diamonds are actually quite rare. It is also true that the diamond extraction process is quite laborious (mines move many tons of dirt for every carat of diamond found) and that diamonds of gem quality are relatively few (only about 1 in 1 million diamonds are 1 carat quality stones; only 1 in 5 million are 2 carat stones; and 1 in 15 million are 3 carats).

Diamond prices are rising with inflation. In some periods, demand is higher than supply, while in other periods it is reversed. In the end, there is always a balance.

The most famous diamonds in the world are the 45 carat Diamond of Hope (and its famous Curse), the mystical Koh-I-Noor Diamond and the 546 carat Golden Jubilee.

The Bokassa Diamond is surrounded by a truly fascinating story. In 1977, a Central African dictator named Jean-Bédel Bokassa declared himself emperor and asked Albert Jolis, president of a diamond mining company, for a diamond ring.

Jolis did not have the money to buy such a large stone, but if he did not deliver one, his company would lose its mining concession in Central Africa. So he came up with a clever solution: Jolis found a large piece of black diamond (a poorly crystallised diamond that usually only fits to be crushed into abrasive powder) that curiously resembled Africa in shape. He ordered the diamond to be polished and mounted on a large ring. A quarter-carat white diamond was then set approximately where the country is located on the continent.

Jolis presented this "unique" diamond to Bokassa, who loved it. He thought the $500,000 ring was worth more than $500,000.

Akbar Shah an Indian diamond with a rough pear-shaped outline and random facets, including two Arabic inscriptions, the first bearing the inscription "Shah Akbar, the Great King, 1028 AD". (The letters mean "Egyptian Year"). The second inscription read "To the Lord of Two Worlds, 1039 A.H. Shah Jehan". It is said that the diamond was part of the original Peacock Throne. Purchased in 1886 in Istanbul by the London merchant George Blogg in 1886, who again cut it from 116 carats (23 g) to a 71.70 carat pear shape (14.34 g), thus destroying the historical inscriptions. Blogg was the last known owner and we do not know where the stone is located.

What is the first record of a man giving a diamond to a woman for her hand in marriage?

In 1477 the Archduke of Austria gave a diamond to Mary of Burgundy. Today, about 500 years later, diamonds are the most popular precious stones in engagement rings.

On average, how old is a diamond?

Diamonds are formed over a period of millions of years deep in the earth's crust - about 150 km (90 miles) deep. Over time, they are pushed to the surface by volcanoes. Most diamonds are found in volcanic rock, called Kimberlite, or in the sea after being carried away by rivers when they are pushed to the surface.

A diamond is 58 times harder than corundum, the hardest mineral on earth, from which rubies and sapphires are formed. Only in the 15th century was it discovered that the only way to cut diamonds was with other diamonds.

What is the biggest diamond in the world?

The biggest diamond in the world known to men is the Cullinan, found in South Africa in 1905. Uncut, it weighed 3,106.75 carats. The Cullinan was cut in the Big Star of Africa (530.2 cts), the Small Star of Africa (317.40 cts) and another 104 diamonds of almost perfect colour and purity. Today these diamonds are part of the British crown jewels.

The Cullinan was three times larger than the next diamond, the Excelsior, which was also found in South Africa. The largest documented polished diamond in the world, which was unearthed in South Africa in 1986, is called the Golden Jubilee. It was cut from a rough diamond of 700 carats and weighs 545 carats. The diamond took almost 3 years to cut, just like the Centenary Diamond, which is part of the British crown jewels. The latter weighs 273.85 carats and is considered the largest perfect diamond in the world.

The largest diamond in the entire universe is thought to be Lucy, a white crystallised dwarf star. It is actually a star burnt by diamonds. It was discovered about 50 light years from Earth in the region of the sky that we call the constellation Centaurus. Its weight is 10 billion trillion trillion carats. Named after the Beatles' song, Lucy in the Sky with Diamonds, the star is technically known as BPM 37093.

In ancient times, what "powers" did people believe diamonds gave it?

In ancient times, diamonds were believed to promote strength, invincibility and courage.

Many jewelers will give you a discount at certain times of the year or when you make a big purchase. At Diamante Sicuro we choose to offer our customers the best prices on their diamond jewellery from the very beginning. Traditional jewellers tend to raise prices to cover overhead costs such as branches, marketing strategies and inventory management. However, thanks to our unique online business model, we are able to bypass these costs - as reflected in our prices. As we are generally 30 - 50% cheaper, while offering the same high quality as other jewellers, there is no room for further price reductions.

At Diamante Sicuro, everything revolves around buying jewellery online. However, you can also make an appointment in our showroom to take a look at the jewellery before making your purchase. Thanks to our business model, we eliminate unnecessary middlemen, so our customers can buy diamond jewellery at a 30 to 50% lower price.

How is the price of Diamond Safe jewellery set?

Because we buy our materials directly from the source, eliminate middlemen and work with small margins, you can also buy jewellery online on Diamante Sicuro at an unbeatable price. Due to constantly changing currency exchange rates and commodity prices, however, we have to regularly adjust the prices of our diamond jewellery.

A specific price is therefore always valid for a limited period of time and is not negotiable.

How can you pay for your jewellery?

Various payment methods are available for the purchase of jewellery online. If you opt for payment by bank transfer, please take into account the time period for processing payments between the different banks. As already mentioned, and as clearly stated in your purchase proposal e-mail, the validity of the offer is limited.

We therefore ask you to make a payment by bank transfer as quickly as possible, so that the specific offer does not expire.

Diamante Sicuro has a very specific way of working compared to local jewellers. Diamante Sicuro only invests in efficiency and does everything possible to avoid unnecessary middlemen. By avoiding expensive marketing campaigns, large stocks, luxury offices and retail outlets, we can offer unbeatable prices. Therefore, our prices are in direct correlation with the quality of the products offered.

A classic local jeweller is not able to buy his diamonds at source, as he has neither the expertise nor the experience of the founders of Diamante Sicuro. The Diamante Sicuro founders have been diamond-makers for several generations, who can buy their splendid high quality diamonds directly at the source where the diamonds are cut. A local jeweller buys the diamonds locally (e.g. in Antwerp) from local diamond traders who in turn buy their diamonds from wholesalers. The diamond passes through various intermediaries in addition to the final purchase price. This has the consequence that their prices will be much higher for diamonds of the same quality, as these additional costs have to be covered.

In addition, Diamante Sicuro builds a rapidly growing customer base around the world in a cost efficient way, thanks to the fact that over 90% of its customers buy online (through our 2-language E-boutique, where customers can pay in different currencies and through various payment methods). Diamante Sicuro has the unique opportunity to offer diamond jewellery at an exceptional quality price to its customers who buy directly through our showroom in Alcamo (TP) - Italy or on our website. Even in our showroom we do not have stock and we start the production process of our diamond jewellery after receiving payment from the customer. A local jeweller, where most of the jewellery is "ready to be taken away", will have to invest in a department shop, luxury shops and related overheads which have a big influence on the final price.

At Diamante Sicuro, there is a commitment to customers to underline the strong link that exists between the prices of the products offered with the intrinsic cost of the underlying components and the materials used for the jewellery. Therefore, Diamante Sicuro always guarantees the best value for money compared to any local jeweller worldwide.

We invest in exceptional quality (in materials, design and finishes), but also in efficiency and we do everything possible to avoid unnecessary intermediaries. No expensive marketing campaigns, luxury offices and retail outlets. Our investment will be immediately visible in Diamante Sicuro diamond jewellery.

Diamante Sicuro is headquartered in Antwerp, renowned since 1447 as the world centre of the diamond trade. More than half of the world's diamond trade takes place in Antwerp. Diamante Sicuro selects diamonds directly from the best suppliers in the world.

Diamante Sicuro buys its diamonds directly from the source and sells its exquisite diamond jewellery collection online and in its showroom to customers.

The direct purchase and sale, avoiding the intermediary, combined with a rigorous stock management, allows Diamante Sicuro to offer the best and widest selection at the best value for money.

And last but not least: since more than 90% of our customers buy online (through our 2-language E-boutique, where customers can pay in different currencies and through a wide variety of payment methods), we are able to manage a rapidly growing customer base worldwide (today Diamante Sicuro sells in various countries) in a very cost-efficient way, without having to invest in a large contingent of luxury retail outlets and related overheads. And this allows us to also offer this same exceptional value for money to customers who choose to visit us in our showroom in Alcamo (TP) - Italy.

In short, Diamante Sicuro promises its customers that its prices are in close correlation with the intrinsic cost of the underlying components and used material of the products offered.

No, it is not possible. In addition, we can only ship your jewellery to an address of your choice once we have received the full purchase price.
