The discovery of precious opal in Ethiopia in 2008 has made a major impact in the gemstone industry. Opal with play of color has always been considered one of the most desired gems in the marketplace, and continues to be one of the top 3 selling colored gemstones in the US. The Ethiopian “Welo” Opal derives its name from the Wollo Province in Ethiopia, which is the only place it has been found to date.

Opal is a hydrated amorphous form of silica and its water content may range from 3 to 21% by weight, but is usually between 6 and 10%. Because of its amorphous character, it is classed as a mineraloid, unlike crystalline forms of silica, which are classed as minerals.

Welo Opal should not be confused with chocolate opal found in the Menz Gishe District, North Shewa Province in 1994. This Shewa Province opal, was mostly dark brown in color, and had a tendency to crack. These qualities made it unpopular in the gem trade. The Wollo Province opal was different from the previous Ethiopian opal finds in that it more closely resembled the sedimentary opals of Australia and Brazil, with a light background and often vivid play-of-color.

With diminishing supplies and mining efforts ramped up, investing in high end precious Welo Opal is a solid investment. High end precious Opal can be hard to find at times since mining and export regulations are very strict, and the Ethiopian Government is undergoing processes which may completely stop the export of rough opal to help boost the local economy. Over the last few years Welo Opal rough prices have started to soar, but still easily affordable in my opinion for such an amazing 10 million year old creation.
