ETHIOPIAN OPAL ROUGH
VERY DARK BASE
OPAL HAS RED BLUE GREEN FALSHED OF COLOR
CHANCE PIECE
UNWORKED
The Stayish black opal mine, active since 2013, is located in the Wollo province of northern Ethiopia. Like the white opal, the black opal is found at the contact zone between the volcanic rock series and the underlying clay-rich layer
The black opal is retrieved from flat tunnels up to 15–20 meters long that are dug horizontally into the mountain slope by local villagers. The material generally comes in nodules and chunks 2–5 cm long, but 10 cm pieces have also been retrieved from this deposit
