Opal is the national gemstone of Australia. Opal is found in Central Australia due to a set of unique geological conditions and almost nowhere else on earth.
A solid opal is a polished stone consisting of precious Opal. A thin Opal may be strengthened by backing it with a dark coloured material, mostly ironstone, to produce a doublet. A triplet has a third layer, a domed cap of clear quartz on top.
The beauty of Opal is its unique display of colours as light is broken up by the three dimensional spherical shaped silica particles making up the Opal. Each Opal is therefore uniquely fascinating. It appears to be alive as the colours flash and change with a unique play of colours as the Opal is viewed from different angles.
