Rio Tinto and The Perth Mint have showcased a A$1.8 million (US$1.36 million) one-of-a-kind coin collection featuring three coloured diamonds from the Argyle Diamond Mine. Known as The Australian Trilogy, the beautiful collectable comprises three precious metal coins each hand crafted with a pink, purple pink and violet diamond unearthed from Rio Tinto’s Argyle Diamond Mine in the east Kimberley region of Western Australia. Unveiled by the Premier of Western Australia, the Honourable Mark McGowan MLA, The Australian Trilogy is issued as legal tender under the Australian Currency Act 1965. The Perth Mint will only ever release one of The Australian Trilogy 2017 Collection.
According to The Perth Mint, its most precious of metals – gold, platinum and rose gold – form three one kilo Australian legal tender coins. Portraying some of Australia's most beloved fauna, the kookaburra, kangaroo and koala, these striking coins become masterpieces with the hand setting of three significant coloured diamonds exclusively sourced from the Argyle Diamond Mine. A managing director with Rio Tinto’s copper and diamonds business, Andrew Kite said, “We are delighted to collaborate with our Select Atelier™, The Perth Mint and our Authorised Partner™, John Glajz, on the exclusive release of this distinctive investment piece. It is a beautiful symbol of the unique treasures of Western Australia and the extraordinary provenance of Australian diamonds and precious metals.” Rio Tinto’s Argyle Diamond Mine produces virtually the world’s entire supply of rare pink diamonds, and yet less than 0.1 per cent of the diamonds produced by the Argyle mine are pink.
