Very low mintage for this perfect series, only 7,500! each coin.
Silver series Treasures of Australia is a beautiful series of locket coins celebrating Australia’s abundance of natural riches.
The third silver release from our Treasures of Australia locket coin series encapsulates natural rough diamonds mined in the East Kimberley region of Western Australia. Sought-after in their own right, rough diamonds are skilfully cut and polished to produce the clarity and sparkle associated with the world’s most celebrated gemstones.
The design surrounds a transparent half-circle locket containing approximately 1-carat of Australian white opals. A token of hope and purity in ancient times, opal is the modern birthstone of people born in October.
Scheduled for release between 2007 and 2011, Treasures of Australia celebrates five glittering prizes found in Australia: Sapphires, Opals, Diamonds, Gold nuggets, and Pearls.

History:
In mineralogy, diamond from the ancient Greek is a metastable allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at standard conditions. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools and the scientific applications in diamond knives and diamond anvil cells.
Because of its extremely rigid lattice, it can be contaminated by very few types of impurities, such as boron and nitrogen. Small amounts of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (lattice defects), green (radiation exposure), purple, pink, orange or red. Diamond also has relatively high optical dispersion (ability to disperse light of different colors).
