Rio Tinto’s rare offering of its large diamonds delivers strong result

07 November 2012
Rio Tinto is delighted to announce the results for its recent sale of some of the largest rough diamonds in the world.

Known as “The Specials Tender”, this invitation- only event provided a glimpse into Rio Tinto’s diverse diamond production. Diamonds greater than 10.8 carats qualify to be included in the Specials Tender and Rio Tinto’s rough diamonds, mined in Australia, Canada and Zimbabwe have all contributed to the 2012 offering.

According to Patrick Coppens, General Manager of Sales for Rio Tinto Diamonds,
“The 94 parcels of diamonds, which included 26 diamonds greater than 20 carats each, attracted very strong bidding and global participation, including Rio Tinto’s Select Diamantaires, who were among the 29 successful companies. The strong participation and results of this Specials Tender, as well as the recently concluded Argyle Pink Diamond Tender, demonstrates the consistent demand and competition for rare and valuable diamonds.”

The most expensive diamond, Diavik Selene, an extraordinary white gem weighing more than 22 carats, was sold to specialist Israeli diamond company, Eshed Diam.

The Specials Tender was also notable for its inclusion of a number large fancy coloured diamonds, including beautiful yellow diamonds from all three Rio Tinto mines.

Rio Tinto is the only mining company that sells its diamonds by mine and country of origin and occupies a unique position as the only miner certified by The Responsible Jewellery Council, the industry organisation committed to promoting responsible practices throughout the jewellery industry from mine to retail.
