Treatment Back To Top
Smoke treatment is a relatively old method of stone treatment that has just recently been reinvented. The process involves wrapping opals into silver foil strips and slowly heating them, allowing the buildup of smoke inside the foil. Carbon formed by the smoke, penetrates deep into the opal stone and stains the original color with deeper and darker tones. Smoke treatment is intended to give the opal brighter play of color, because the bright colors contrast better on darker backgrounds. More about treatments
About Opal
More than any other gem, each opal is distinctly an individual. No other stone has as rich and varied a folklore. Opals are also the most delicate gems commonly worn. They require special care to insure their health and longevity.

Opal's fire was long thought to be the result of iridescence. However, with the advent of scanning electron microscopes, we now know that it is a result of diffraction.

Opal is relatively soft, with a rating of 5.5-6.5 on Mohs scale. Despite its frequent use in rings, opal is a poor choice for a ring stone; it is much better suited to earrings, pins, and pendants.

Major suppliers include Australia, Brazil, Mexico, and the US. Values are normally determined by the presence and nature of color flashes.
