The 3.14 carat polished emerald cut diamond, known as The Argyle Alpha, is part of the line-up of 63 rare pink, red and violet diamonds in the 2018 Argyle pink diamonds tender. Following viewings in Sydney the collection will be showcased in Hong Kong and New York with bids closing on October 10.

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. The combination of strong demand and extremely limited world supply continues to support significant value appreciation for Argyle pink diamonds,” said Rio Tinto CEO Jean-Sebastien Jacques .
The 2018 Argyle pink diamonds tender is named ‘Magnificent Argyle’ in honour of Argyle’s role in charting the history of the world’s most coveted diamonds. The 63 diamonds in the tender weigh a total of 51.48 ct, including five fancy red diamonds, two Purplish Red diamonds and three Violet diamonds.
