Opal Capital of the World
Coober Pedy


•  Opal is a form of silica, chemically similar to quartz, but containing water within the molecular structure.
Precious opal generally contains from 6-10% water and consists of small silica sheres arranged in a regular pattern.

•  Opal occurs in two varieties, precious opal and common opal (also known as potch)Colour in precious opal is caused by the regular array of silica sheres diffracting white light and breaking it up into the various colours of the spectrum.
The diameter and spacing of the spheres controls the colour range.

•  Opal colours also depend on the angle of light incidence and can change or disappear when the gem is rotated.
In common opal or potch, the silica sheres are irregular in shape and molecular structure and accordingly whitw light is unable to be diffracted and consequently there is no colour.

   The Desert Cave Hotel is an
   oasis in the desert.

The Olympic Australis' from Coober Pedy is said to be the world's largest piece of uncut precious opal and weighs 3,5 kilograms. Its name comes from the fact the piece was found in 1956, the year the Olympic Games were held in Melbourne, Australia.
