De Beers Auction Sales, which carries out auction sales of rough diamonds, introduced "forward contracts" for sale, through which De Beers Group customers are given the opportunity to secure a long-term supply at auctions.
The company's statement, e-mailed to Rough & Polished, says that the new offer will complement the usual auction sales with immediate delivery for cash.
The purchase price of the required amount of rough diamonds under the forward contract will be determined based on the price offer of the customer in relation to the spot price for the same type of goods at the auction, when the deadline for the performance of the contract, the Group reports.
At the first auction with the conclusion of forward contracts, held on Tuesday, registered customers of De Beers Auction Sales made applications for future supplies for a period of up to three months, the statement said.
Forward auctions with the opportunity to participate in bidding for future supplies of rough diamonds during the 12-month period will be introduced in 2014.
