ABOUT ETHIOPIAN OPALS
Ethiopian opals are not only beautiful, but they generally cost less than similar-quality opal from Australia. People now go to the store looking for “Welo opals” or “Ethiopian opals.” They also use the internet and search for these opals by name. This surge of public awareness has developed in just a few years without a major mining company or jewelry brand spending millions of dollars to promote them. This popularity is being driven by the beauty of Ethiopian opal and their current attractive prices.
Smoke Treatment
Smoke is a suspension of very fine particles in air or gas. Fine smoke particles can enter the pore spaces of opal and change its body color. The smoke treatment can be done by wrapping the opal in paper and heating the paper to a temperature that produces smoldering. The smoldering paper releases fine particles of black soot that enter the pores of the opal and darken its body color. The darker body color contrasts with the opal’s play-of-color, making it appear stronger and more obvious.
Smoke treatment can sometimes be detected by looking for black soot particles during microscopic examination. These can often be seen individually, or in concentrations along microfractures within the opal. Laboratory tests, such as Raman spectroscopy, have the ability to detect smoke treatment because they can detect carbon, which is normally absent in opals of volcanic origin.
