General Gemstone Details
Opal is a hardened silica gel, usually containing between 5-10% water. Therefore it is noncrystalline, unlike most other gemstones. There are two variety: precious opal, which shows flashes of color or iridescence, depending on the angle of viewing and light; then there is common opal whish is often opaque and displays no iridescence. The iridescence of precious opal is caused by the way the structure, or regular arrangement of tiny silica spheres, diffracts light.
Precious opals occur in a great range of color and varieties. White opal, black opal, fire opal, matrix opal, blue opal, Peruvian blue opal, pink opal...this list is extensive.
Scientific Properties:
Mohs Hardness of 7 with a trigonal crystal structure.
Opal is a mineral species which is amorphous in structure, (without form). It has a chemical composition of SiO2.nH2O. (water content usually 3 to 14% by weight, but sometimes as high as 20%). It is transparent to opaque in appearance and is usually seen cut into cabochons, carvings, and beads and is occasionally faceted. Refractive index is around 1.450 but can go as low as 1.42 depending on the type of Opal. The specific gravity is 2.15 and the hardness is soft, being a 5. Opal is very sensitive to heat or sudden change in temperature. Never clean your Opal jewelry in an ultrasonic cleaner, it will crack the Opal.
In other words...opal is created of tiny spheres of amorphous silica gel, which gives it its "Fire" and glittery play of colors. A non-crystalline stone, it is possible for the opal to dry out and crack. It is a delicate stone, and can have as much as thirty percent of it's body weight in encapsulated water. This too explains why too much heat can cause an opal to quickly lose it's luster, and why a crack or craze to the surface may occur by moving from a hot room to the cold outdoors.
