Intense light refraction on this high grade Australian Opal.
Opal is a non-crystalline, hydrated form of silica.
On average, the water content is around 10%. If the opal dries out due to exposure, it can become brittle and lose some luster. If you have any opals, periodically soaking them in water will prolong their life and beauty.
Quartz is composed of crystalline silica, giving it an organized structure. Opal, on the other hand, consists of micro silica spheres of various sizes.
These spheres refract light. The color and intensity of the light flash is determined by the way the spheres are packed together. Some opals contain other minerals or grow within a matrix which can affect their appearance.
Opal is the birthstone for those born in October.
It is considered by some to be a lucky amulet that attracts wealth and abundance. Whether or not it holds magic, the light and color pleases the eyes and the spirit.
