Our profession as a diamond dealer in Paris

The diamond dealer's activity mainly consists of selling diamonds. The diamond dealer can intervene upstream of the sale, by cutting the stone in the most suitable way for the rough diamond in order to reveal its beauty. Whether it is round, square, oval, cushion or radiant cut, the cut of the stone is decisive in the way the diamond reflects light. In addition to cutting, the diamond dealer can 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 can also appraise diamonds 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 sell diamonds and valuable jewelry, and they assess them based on their own characteristics — weight, color, clarity, cut quality — rather than a display case price. It is a difference in profession, 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 intermediaries: the offer is firm and known in advance, and payment occurs as soon as agreement is reached. There is no starting price, no sale delay, and no commission taken from the final proceeds. In return, 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 benchmarks, valid everywhere: the appraisal is carried out in front of you and explained criterion by criterion; the professional has verifiable qualifications — in our case, state-certified gemologists; the transaction is recorded in the police ledger and results in a written transfer contract; your identity is verified, as required by law. A house that refuses to explain its calculation, or pressures your decision, should raise your attention.

Where to find a diamond dealer in Paris

The diamond trade is historically concentrated between the Rue du Temple, the Marais, and Place Vendôme. Our offices are located at 43 rue Beaubourg, in the 3rd arrondissement, a stone's throw from the Rambuteau metro. We welcome you Monday to Friday, from 10 a.m. to 1 p.m. and from 2 p.m. to 6:30 p.m., with or without an appointment. You can also get an initial price range remotely, from photos, before any trip.
