Our Profession as a Diamond Dealer in Paris
The activity of a diamond dealer mainly consists of selling diamonds. The diamond dealer can intervene before the sale by cutting the stone in the most suitable way for the rough diamond in order to reveal its beauty. Whether round, square, oval, cushion, or radiant, the cut of the stone is crucial in how the diamond reflects light. In addition to cutting, the diamond dealer can also handle polishing, that is, polishing the diamond to remove impurities that may be present on the rough diamond.
The work of the diamond dealer 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 perform diamond appraisals and buy them back to resell them later.
