Selling Our Diamonds: From Mine to Market
De Beers sells rough diamonds through two channels: Global Sightholder Sales and Auctions. Our rough diamond sales operations are in key global trading hubs, including Belgium, Botswana, Dubai, Hong Kong, Namibia and South Africa.
GLOBAL SIGHTHOLDER SALES
Global Sightholder Sales sells around 90% of De Beers Group’s rough diamonds by value to customers known as Sightholders. These customers are among the world’s leading diamantaires and are active in the major diamond centres.
Sights - sales events for Sightholders – are held 10 times a year in Botswana, Namibia and South Africa, where customers inspect their rough diamond allocations before deciding whether to purchase them. These diamonds originate from De Beers Group’s owned and joint venture operations, and from mines that are certified against the Responsible Jewellery Council Code of Practices and compliant with the Best Practice Principles.
