The future is very bright for Ethiopian opals. They are becoming much more visible in the gem and jewelry market, and the gem-buying public is becoming aware of them. All of this has occurred without a major mining company or jewelry brand spending millions of dollars to promote them. They occur in a variety of translucent to transparent basecolors with vivid play-of-color in a variety of patterns. They currently sell for very reasonable prices when compared to similar-appearance material from Australia. Significant amounts of Ethiopian opal are being produced and the country might become the first important challenger to Australian opal, which has dominated the world opal market for over 100 years. Ethiopian Opal is a new variety of opal discovered in Wollo province of Ethiopia. It is highly valued for its vibrant body hues, bold color flashes and patterns. These opals are superior in terms of quality but are relatively cheaper than the other popular origin varieties such as Australian 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. faceted Ethiopian opal Faceted Ethiopian opal: Many translucent to transparent pieces of Ethiopian opal are faceted, such as these four small trillion-cut gems The most important opal discovery in Ethiopia to date was made in 2008 near the town of Wegel Tena in the Wollo Province in the northern part of the country. This opal can have vivid play-of-color flashing from a body color of clear, white, yellow, orange, or brown. It is more stable than the North Shewa opal. This material quickly became known in the trade as “welo opal,” but the names “wollo” and “wello” are also encountered. Much of the welo opal is produced from a single area of stratified volcanic rocks. The main vein is an opalized rhyolitic ignimbrite up to one meter thick that overlies a base of clay. The opal likely formed as silica-bearing waters accumulated on top of the impermeable clay. Silica gel precipitated in the pore spaces of the ignimbrite and was later transformed into opal.
