What is an opal
Where does opal come from
How Australian opal was formed
Colour in opal
96% of the world’s precious opal comes from isolated areas in the outback of Australia. A small amount of precious opal is found in Brazil and Mexico, the complexity of colour and pattern of these opals is incomparable to that of Australian precious opal. Common opal can be found in a limited number of countries, and is widely found in opal regions but contains no colour. Australian stones can easily be distinguished by their brilliance and play of colour.

The opal fields of Australia are spread around the eastern regions of central Australia, across the states of Queensland, New South Wales and South Australia -
  • Black Opal comes from Lightning Ridge in New South Wales.
  • Light or White Opal is mined principally from the South Australian fields of Mintabie, Coober Pedy and Andamooka.
  • Boulder Opal is from Central Queensland in the areas surrounding the townships of Quilpie and Winton.
