Rio Tinto has launched a collection of rare pink diamonds from its Argyle mine, which has been specially curated to showcase the full color palette of the deposit’s stones.
The Argyle Pink Everlastings collection contains 64 lots and has a total weight of 211.21 carats, with each individual stone weighing 0.14 carats or below, Rio Tinto said Monday the 9th. The miner will provide a certificate of authenticity for each lot purchased, it noted. Rio Tinto will only produce approximately 100 more carats of similar diamonds before the Western Australia mine closes in 2020, it explained, in an effort to emphasize the rarity of the stones.
“The accumulation of these diamonds from a certifiable source in various shapes, sizes and colors is the result of a painstaking endeavor, unlikely to be ever repeated,” said Alan Chirgwin, vice president of sales and marketing at Rio Tinto.
The miner will auction the collection alongside the stones it offers in its annual Argyle Pink Diamonds Tender, which will be held in Singapore, London, New York and Perth, Australia, with bids closing on October 9.
