Rio Tinto will offer a 3.14-carat, vivid pink diamond at its 2018 tender, the largest stone of its color in the history of the annual sales event.
The emerald-cut Argyle Alpha (pictured) is one of 63 rare pink, red and violet diamonds — weighing a combined 51.48 carats — featuring in this year’s pink diamond tender. It is part of a collection of six “hero” diamonds the miner will offer at the sale.
“Rio Tinto’s Argyle mine is the world’s only source of these highly coveted pink, red and violet diamonds, and we expect considerable interest in this year’s collection,” Rio Tinto CEO Jean-Sébastien Jacques said Thursday. “The combination of strong demand and extremely limited world supply continues to support significant value appreciation for pink diamonds.”
This year’s tender, which the company has called Magnificent Argyle, also includes the Argyle Muse, an oval-cut, 2.28-carat stone, which is the largest purplish-red diamond ever offered at the tender, and came from a 7.39-carat rough. A second diamond, cut from the same stone, will also be up for sale.
The other hero diamonds include the square-radiant-shaped, 1.29-carat, fancy vivid purplish-pink Argyle Maestro; the princess-shaped, 1.57-carat, fancy dark grey-violet Argyle Alchemy; the Argyle Odyssey, a round brilliant, fancy intense pink stone weighing 2.08 carats; and the radiant-shaped Argyle Mira, a 1.12-carat fancy red.
Rio Tinto will unveil the gems at a world exclusive preview in Sydney, and will also showcase them in Hong Kong and New York. Bidding for the diamonds closes on October 10.
The company held its first pink diamond tender in 1984.
