Characteristic of this kind of opal is the transparent to translucent bodycolor. This can be clear as water or can have a hint of very pale blue to a very light yellow orange. In addition to this bodycolor, Water Opals can show a wonderful play-of-color consisting of all the colors of the spectrum. This play-of-color is known as opalescence and is due to the opals contents of silica gel and 3 to10% water. Embedded in the silica gel are tiny spheres of christobalith through which the light is refracted and separated into different color beams. The most transparent of these wonderful opals have smaller amounts of silica gel between the spheres.
Water Opals are usually cut into cabochons. Only the completely clear and transparent stones may be faceted.
With its gently shimmering pastel colors, Water Opals are said to be the stones of true artists and creative people. They inspire and encourage imagination and creative spirit.
