The Argyle diamond coin trilogy sold within a month, according to a press release from Rio Tinto. "The Australian Trilogy", is an US$1.4 million (AUD$1.8 million) one-of-a-kind coin collection featuring a pink, purple pink and violet diamond from Rio Tinto’s Argyle Diamond Mine in the east Kimberley region of Western Australia. Released by The Perth Mint, The Australian Trilogy was sold to an anonymous collector from Asia within a month of its unveiling. The Perth Mint has worked in collaboration with Mr John Glajz, an Authorised Partner of Argyle Pink Diamonds, to create a number of limited edition gold and pink diamond ingots and coins during the past five years, which have been in strong demand from investors, collectors and diamond experts.
Mr Glajz said “I am delighted with the sale of The Perth Mint’s Australian Trilogy. We have seen and continue to see, strong demand from this high end of the luxury market. The coveted Australian Trilogy speaks the language of exclusivity, desirability and collectability.” 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. The Australian Trilogy will be exhibited at The Perth Mint until Monday 31 July 2017. Describing the coins, the Perth Mint says it used its most precious of metals – gold, platinum and rose gold – to create 3 one kilo Australian legal tender coins, portraying some of Australia's most beloved fauna: the kookaburra, kangaroo and koala.
