(IDEX Online) - Rio Tinto has sold The Australian Trilogy, an 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 by the Premier of Western Australia, Mark McGowan.
The Perth Mint has worked in collaboration with 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.
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."
