This is a third gold release from the mint Treasures of Australia locket coin series encapsulates natural rough diamonds mined in the East Kimberley region of Western Australia.

The Argyle Diamond Mine is a diamond mine located in the East Kimberley region in the remote north of Western Australia. Argyle is the largest diamond producer in the world by volume, although due to the low proportion of gem-quality diamonds, is not the leader by value. It is the only known significant source of pink diamonds, producing over 90% of the world's supply. It additionally provides a large proportion of other naturally coloured diamonds, including champagne, cognac and rare blue diamonds. Argyle is currently transitioning from an open pit mine to an underground mine. The Argyle mine is owned by the Rio Tinto Group, a diversified mining company which also owns the Diavik Diamond Mine in Canada and the Murowa Diamond Mine in Zimbabwe.
The coin’s reverse design portrays an abstract interpretation of Australia’s stark and beautiful landscape. The design surrounds a transparent half-circle locket containing approximately 1-carat of Australian natural rough diamonds. The most desirable of all gemstones, diamonds are a traditional symbol of love, and the modern birthstone of people born in April.
Issued as legal tender under the Australian Currency Act 1965, the coin bears the Ian Rank-Broadley effigy of Her Majesty Queen Elizabeth II on its obverse.
