Opal in Ethiopia was discovered in 1994 and has since grown to have an impact on the world market with its high quality. Precious, fire, and black opals are now being mined in Ethiopia, under the name \"Welo/Wollo/Wello or Ethiopian Opals\". The best and most abundant opals are found in Ethiopia\'s Wollo region, in the north of the country, they have a wonderful variety of colors and body variety. Opals from Ethiopia vary widely but the most abundant are the stable and transparent ones that offer a beautiful play of colors within them.
