Diamond dealer


Diamond dealers since four generations in Antwerp, we created in 1999 the French website i-diamants.com. Each purchase or sale of diamonds is made in the respect of the rules of the know-how and the tradition of quality of Antwerp.


As the world center of diamonds for several centuries, Antwerp is the cradle of the know-how of our diamond trade. Diamonds, whether still rough or already cut, are a material whose quality and price are difficult to evaluate for the uninitiated. Understanding is the first step to making a good choice. The first role of a diamond dealer is to accompany you in your approach and help you choose the ideal diamond.


With i-diamants, we try to give you the essential information via a diamond guide explaining what you absolutely need to know to buy a diamond in France or abroad. For more information, our customer service answers you by email or by phone from the contact details and contact forms available on the site. We can also receive you by appointment in Paris, Nice, Cannes and Monaco.


We offer on our site a large stock and online price list of cut diamonds in all weights and qualities of color, clarity and cut, as well as a collection of the great classics of French jewelry and creative pieces.


Expert in Diamond and Gemmology


To help you buy a diamond from Antwerp, i-diamants offers a Diamond Selection documented and commented in a "Diamond Sheet" with a visualization of the diamond certificate, including the drawing of the independent gemologist to represent the degree of purity. It is easy to get lost or to make a mistake among the many possible choices, as there are so many combinations of weight and quality! Together, we will select the key elements to remember when choosing the gem of your dreams.

Each diamond is unique, whether it is rough or cut. The diamonds we offer are all certified by one of the three largest gemological laboratories: HRD, IGI and GIA certificates. The certificate number is laser engraved on the diamond's circumference to ensure that the stone matches the certificate.

As diamond experts, our motto "Integrity Inside, Beauty Outside" underlines our attitude of respect for the customer and for the product:

1. Integrity of the maximum information on the diamond offered.

2. Optimal beauty of each diamond and in particular of the favorite diamonds of the selection of the selective catalog of i-diamants (selection carried out by a wise diamond dealer).

Exceptional jeweler

  Diamond jeweler
  The hand of the jeweler

Once you have chosen a diamond, we also offer you the possibility of creating a unique and custom-made piece of jewelry by our high jewelry workshop. Simply send us a sketch or photos and we will develop for you in 3D the jewel of your dreams, in gold or platinum according to your choice between these two precious metals. It will then be worked by hand by our diamond jewelers in Nice and Paris.

i-diamants is an online jeweler and not an online jeweler because we do not sell any brand of jewelry, but only jewelry made to measure for you, from the design to the final polishing, through the choice of gems (diamond and / or other gems and precious stones) and their setting by expert fingers. We offer you a collection of classic jewelry (solitaire, wedding rings, engagement rings, earrings, pendants...) to be customized according to the diamond and the size of your choice, as well as original creations and exceptional jewelry in gold and diamond.


As a specialist in made-to-measure jewelry, we will accompany you in the creation of a unique piece of jewelry created from scratch together, thanks to an exchange between your desires and our diamond and jewelry know-how. We have all the digital tools (3D technical drawings, photo renderings and 3D videos) so that you can make your modifications and your choice remotely by exchanging emails and can also receive you by appointment in Nice, Cannes and Monaco.

We work with the best experts and goldsmiths to create frames with finishes, settings and polishings worthy of the know-how of French high jewelry. Gold and platinum are the main precious metals we use for our ring, wedding band and diamond pendant creations. Our models, proposed mainly in all gold and diamond, can be set with other types of gems (sapphire, ruby, emerald or other precious stones and fine stones) on your request.

Diamonds and precious jewelry are expensive! The most obvious advantage of buying on our website rather than in a jewelry store is to benefit from lower structural costs and much more competitive prices, often 25% to 50% lower than in a jewelry store. Other advantages are accessibility, time and discretion: what a comfort to be able to take the time to choose your diamond and your jewel incognito from home! Our customer service by email and phone will also allow you to ask all the questions you want and over several days, without having the inconvenience of going several times to a jewelry store.
