MAKE AN AWESOME RING OR PENDANT
Opal is a very common material that is found throughout the world. Most of this opal is "common opal" or "potch" which has a milky or pearly luster known as "opalescence". However, rare specimens of opal produce brilliant color flashes when turned in the light. These color flashes are known as a "play-of-color". Opal specimens that exhibit a play-of-color are known as "precious opal." If the play-of-color is of high quality and large enough to cut, the material can be used to produce valuable gemstones.
A play-of-color in opal can be observed under three situations: 1) when the stone is moved, 2) when the light source is moved, or, 3) when the angle of observation is changed. The video at right illustrates "play-of-color" in an Ethiopian Welo opal.
Areas within an opal that produce a play-of-color are made up of microscopic spheres of silica arranged in an orderly network. As the light passes through the array spheres it is diffracted into the colors of the spectrum. The size of the spheres and their geometric packing determine the color and quality of diffracted light.
Famous mining areas in Australia include: Coober Pedy, Mintabie, Andamooka, Lightning Ridge, Yowah, Koroit, Jundah and Quilpie. Other countries that produce precious and fancy varieties of common opal include: United States, Mexico, Hungary, Indonesia, Brazil, Peru, Honduras, Guatemala, Nicaragua, Slovakia, Czech Republic and Ethiopia.
