With an extensive range of products, carefully prepared from a run of mine (ROM) supply of De Beers rough diamonds, Auction Sales customers can combine rough purchases in our single-unit spot auctions, multiple-unit spot auctions and forward contract auctions to create bespoke supply portfolios to help them meet their business objectives.

Our auctions have been designed to cater to all our customers’ requirements, irrespective of the scale and scope of their businesses.


These auctions provide customers with a one-off opportunity to purchase rough diamonds.

‘Single-Unit’ spot auctions: Customers may purchase a single unit of rough diamonds at each event.

‘Multiple-Unit’ spot auctions: Customers may purchase multiple homogeneous units of rough diamonds at the same price, at each event.


These auctions provide customers with the opportunity to purchase short and medium-term supply contracts of multiple homogenous units of rough diamonds for delivery at future pre-determined dates.
