Marvelous 23 carats Ethiopian Welo opal with superb play of color.

Ethiopian Opal has been mined since 2008. The entire region around Wegel Tena consists of a volcano-sedimentary sequence with alternating layers of basalt and rhyolitic ignimbrite. Over the entire region, only one thin seam is mineralized with opal. The opal is extracted by artisanal miners using picks, hammers, and shovels.
