3.66ct Crystal Opal - 10 x 15 x 4mm

Crystal opal has a translucency that allows deeper colours to be seen. Australian crystal opal is the best in the world. It can be found in all the opal regions within Australia. It is often the favourite variety of opal traders and miners because of its high clarity. In Opal, clarity means how crisp and sharp the colour is and how deep the colour seems to penetrate. An opal with a haze of grey or white over the colour would be regarded as having low clarity. The higher the clarity the rarer the opal and the more an opal is worth. Dark and black crystal opal is also highly valued and the best pieces are often regarded as the world's best variety of opal.
