EWOBM-1oz and EWOBM-2oz: 1 and 2 ounce lots of rough Ethiopian Welo opal. Was $175/ounce or $295.00/2 ounce lots: now $150/ounce or 2 ounce lots for $275.00. Medium to large easily cut sizes for the beginner or experienced opal cutter. This isn’t our top grade of rough Welo opal but you will certainly be able to cut some lovely opal cabochons with this opal. The photograph is a close up of a random selection from a kilo of rough “B” Grade Welo opal.
