This pink diamond gold coin is set to make history
The Perth Mint unveiled Tuesday a gold coin worth over US$6,000 (almost A$9,000), which features a rare Argyle pink diamond to depict a Kimberley sunset over a boab tree in the northwest wilderness region of Western Australia.
Struck in two ounces (56 grams) of 22-karat gold to proof quality, the 2015 Kimberly Sunset Pink Gold High Relief coin comes at a special moment, says the Mint, as the end of mining at Rio Tinto’s (LON:RIO) Argyle mine is around the corner.
Reports estimate the Argyle open-pit mine, where the coin's gem is from, will remain open about five more years.
The reverse side of the piece, the first Australian legal tender gold coin to include a rare Argyle pink diamond, features an effigy of Queen Elizabeth II and the monetary denomination.
