Our diamond dealing profession in Paris

The activity of a diamond dealer mainly consists in selling diamonds. The diamond dealer may be involved upstream of the sale, cutting the stone in the manner best suited to the rough diamond in order to reveal its beauty. Whether round, square, oval, cushion or radiant, the cut of the stone is decisive in how the diamond reflects light. In addition to cutting, the diamond dealer may handle polishing, that is, polishing the diamond to remove impurities that may be found on the rough diamond.

The diamond dealer's work is therefore crucial to guarantee the quality of the stone. It is also the diamond dealer who will sell the diamond and set its price as a specialist.

The diamond dealer may also carry out diamond appraisals and buy them back to resell them.

What is a diamond dealer, and how do they differ from a jeweler?

A diamond dealer is a trader specializing in the stone itself. They buy and resell diamonds and valuable jewelry, and they evaluate them based on their own characteristics — weight, color, clarity, cut quality — and not based on a retail price. It is a difference in trade, not degree: a jeweler sells creations, an auctioneer organizes public sales, a diamond dealer buys directly.

What this changes when you sell

Going through a diamond dealer means dealing without an intermediary: the offer is firm, known in advance, and payment occurs upon agreement. There is no starting price, no sale delay, no commission taken from the final product. On the other hand, you must accept that the proposed price is a trade price, based on real market rates rather than an optimistic estimate.

How to recognize a serious diamond dealer

A few simple markers, valid anywhere: the expertise is carried out in front of you and explained criterion by criterion; the professional has a verifiable qualification — with us, state-certified gemologists; the transaction is recorded in the police book and results in a written transfer contract; your identity is verified, as required by law. A house that refuses to explain its calculation, or that rushes the decision, should draw your attention.

Where to find a diamond dealer in Paris

The diamond trade has historically been concentrated between rue du Temple, the Marais and Place Vendôme. Our offices are located at 43 rue Beaubourg, in the 3rd arrondissement, just steps from the Rambuteau metro station. We welcome you Monday to Friday, from 10 a.m. to 1 p.m. and from 2 p.m. to 6:30 p.m., without an appointment or by booking a slot. You can also send us photos before any visit: we will tell you if your piece matches what we are looking for.
