A collection of 65 rare pink and red diamonds from the Argyle mine in the North West of Australia has been sold in a global tender.
The Argyle Pink Diamonds Tender, known as the Connoisseurs Collection weighing a total of 44.14 carats and including four what are known as fancy red diamonds, went to bidders from 11 countries.
Rio Tinto, the owner of Argyle, doesn’t reveal what the tender winners paid for their diamonds.
However, pink diamonds can fetch 50 times more than the more common white diamonds. They often get $1 million a carat.
Based on that the 2015 Argyle collection would have brought in more than $40 million. The most expensive pink diamond sold was the Graff Pink, a 24.78 carat fancy intense pink diamond, sold at Sotheby’s in 2010 for $US46 million.
