2008 Treasures of Australia Series Opals - 1oz silver proof coin COA 444. The coin's reverse protrays an abstract interpretation of the Australian landscape, one of the world's richest sources of gems and precious metals.
The coin also incorporates a transparent locket containing approximately 1-carat of Australia white opals. Fine opal is sought-after for its brilliant iridescence - unique and magical interplays of colour created by the inner diffraction of white light into dazzling rainbow hues. The more intense the'play of colour' from within, the more valuable the opal. Australia produces around 95 per cent of the world's opals, including gem quality opal from the South Australian town Coober Pedy, and coveted Black Opal from Lightning Ridge in New South Wales.
A token of hope and purity in ancient times, opal is the modern birthstone of people born in October. No more than 7500 of these coins will be struck by The Perth Mint. The item "2008 Treasures of Australia Series Opals 1oz silver proof coin COA 444" is in sale since Friday, January 17, 2014.
