The name Opal was derived from Sanskrit “upala“, meaning ”valuable stone“. This was the root for the Greek term “opallios”, which translates as “colour change”. Australia is the classical Opal country and today is the worldwide most important supplier of Fine Opals. Almost 95 per cent of all Opals come from Australian mines. The remaining five per cent are mined in Mexico, and in Brazil’s north, also in the US states of Idaho and Nevada, but recently the stones have also been found in Ethiopia and in the West African country of Mali.
