Avika Certified Natural Opal Gemstone

Avika Certified Natural Opal Gemstone is typically untreated, but it may be impregnated with oil, wax, or plastic to enhance color and stability. It may also be layered (as in doublets or triplets) for durability. \'Smoking\' treatments are now more common than before. \'Smoking\' of opal is done to darken body color which enhances play of color, most often seen with Ethiopian opal. There are forms of synthesized opal available. Technically they are \'imitation opal\' as they often include substances like plastic, which are not found in natural opal.
