Welo Opal "Ethiopian Opal"
Some of the opals mined in Ethiopia are hydrophane opals, particularly from the Welo rocks.
Hydrophane Opal is a new word made to indicate a specific Opal kind. Opals have been dug for millennia in Europe and furthermore over 165 years in Australia. In any case, the finding of opals from Ethiopia and Hydrophane has really been around for pretty much 20 years. Business
