The Premier of Western Australia, the Honourable Colin Barnett MLA, today unveiled the world’s first coin to feature a significant red diamond from Rio Tinto’s iconic Argyle Diamond Mine.

A world exclusive from The Perth Mint, the Kimberley Treasure coin is the only coin in its class. 

Valued at $1million, the breathtaking collectable has been crafted from one kilogram of 99.99% pure gold, and features a radiant 0.54 carat red diamond unearthed from the famed outback mine in the East Kimberley region of Western Australia.
