Beneath the ancient boab trees in the heart of the East Kimberley in Western Australia’s far north, the world’s rarest diamonds were formed more than a billion years ago. Argyle pink diamonds are a true Australian treasure, limited by nature and highly sought after by collectors and connoisseurs. Each of the Kimberley Sunset coins incorporates a superbly hand set Argyle pink diamond.
Struck by The Perth Mint from 22-carat (91.67%) pink gold in proof quality, the coin contains 2oz of pure gold and an Argyle pink diamond of between 0.035 and 0.040 carats.
The coin’s reverse depicts a boab tree amid a Kimberley landscape at sunset. An Argyle pink diamond embedded near the horizon represents the setting sun. The design includes the inscription KIMBERLEY SUNSET, the 2015 year-date, and The Perth Mint’s ‘P’ mintmark.
The coin’s high relief reverse and obverse are minted on concave surfaces to ensure the optimum flow of metal is achieved by the strike of the die.
Issued as Australian legal tender under the Australian Currency Act 1965, the coin’s obverse depicts the Ian Rank-Broadley effigy of Her Majesty Queen Elizabeth II and the monetary denomination.
The Perth Mint will issue no more than 440 of the Kimberley Sunset 2015 2oz Pink Gold Proof High Relief Coin in this packaging, from a maximum mintage of 500.
Each coin is housed in a black designer case, and is accompanied by a numbered Certificate of Authenticity.
