On June 29, De Beers will allow traders in exceptional polished diamonds to transact anonymously for the first time via the De Beers Auction Sales platform. The first auction will include about 50 exceptional polished stones.
According to De Beers, all sellers must be registered “and comply with the De Beers Auction Sales Diamond Trading Standard, which sets out strict criteria in relation to seller integrity, diamond provenance and product integrity. Purchasing is only open to Registered Buyers”.
All exceptional polished stones will be greater than 2.5-carats or of fancy colour, and verified by De Beers Group’s own International Institute of Diamond Grading & Research’s labs to confirm they are natural and untreated.
Two auction will be held on June 29: The auction for third-party exceptional polished stones, as well as the first auctions of De Beers Group’s own polished diamonds, manufactured directly from its own rough. De Beers stresses that “The separate auctions will be held back-to-back, allowing buyers to source all polished on one day”.
