The diamond trade operates as a sophisticated and profitable sector that depends greatly on the expertise and knowledge of jewel merchants. These experts handle the buying and selling of the finest stones, acting as central figures in the gemstone industry.

What Is a Diamond Dealer?
Professional gem dealers work as intermediaries between the primary sources and gemstones retailers, obtaining raw, uncut diamonds that will later become polished gems available to the public. This process requires a keen eye for gem grading, knowledge of market trends, alongside strong bargaining tactics.

A gem dealer’s knowledge is primarily focused on the key characteristics of diamonds—cut, hue, purity, and carat weight. Having a deep grasp of these elements helps a diamond dealer to assess the worth of a diamond and determine its market potential. Such knowledge is crucial for closing transactions in the intense competition of diamond dealing.

The Diamond Dealer’s Supply Chain
Gem merchants commonly source their diamonds from numerous locations that are known for their diamond production, like South Africa, Russia, Canada, and Australia. Such areas produce a large quantity of the world’s rough gems, before being transported to diamond markets in Belgium (Antwerp), the U.S. (New York), the UAE (Dubai), and Asia (India).

Beyond sourcing diamonds from mining companies, certain merchants acquire gems at high-end auctions, private collectors, during estate auctions. A broad range of supply channels allows diamond dealers to offer a broad selection of diamonds, ranging from affordable pieces to exceptionally valuable gems.

How Do Diamond Dealers Establish Credibility?
Trust and reputation are vital for the success of a diamond merchant. Since diamonds are a high-value commodity, investors require full trust that the diamonds they acquire are certified and properly graded.

Therefore, gem dealers often rely on independent grading certificates from reputable institutions like the GIA (Gemological Institute of America). Additionally, establishing strong relationships with retailers and sellers is critical in securing deals in the diamond industry.
