The Diamond Trading Company (DTC) is the rough diamond distribution arm of De Beers, and is the world's largest supplier of rough diamonds, by value.
Beneficiation is embedded in the DTC business model. This means that we have a fundamental commitment to working with our partners to ensure the growth of business activities catalysed by the diamond industry which add value to the economies of diamond producing countries.
Diamdel is the world leader in the online auctioning of rough diamonds. We actually pioneered the approach in 2008 when we broke with 44 years of traditional, direct sales to hold the industry's first online, international auction sale.
