Rio Tinto is delighted with the results of its recent “Specials” tender, which showcases the finest, large rough diamonds from its three operating diamond mines.

Diamonds greater than 10.8 carats in qualities that qualify as “special” and Rio Tinto’s rough diamonds, mined in Australia, Canada and Zimbabwe, all contributed to this collection, which was offered for tender in Antwerp and Israel from October 3 to 24.

This collection was comprised of 104 parcels of diamonds and was notable for the large fancy cognac diamonds from the Argyle mine in Western Australia. The most valuable diamond was a 74 carat diamond from the Murowa mine in Zimbabwe.

Patrick Coppens, the general manager of sales for Rio Tinto Diamonds, said, “This Specials tender showcases the unique portfolio of Rio Tinto’s diamonds mines and the results reflect the strong demand and resilience for diamonds at this end of the market.”

More than 100 diamond specialists from around the world were invited to bid on the Rio Tinto Diamonds Specials Tender. Participants placed their bids via Rio Tinto Diamonds online bidding platform. Thirty-four companies were successful with strong representation from Israel.

Rio Tinto is the only mining company that sells its diamonds by mine and country of origin.
