Origins and deposits of opal
Its name comes from the Sanskrit upala, “precious stone,” from which Greek drew opallios and Latin opalus. Archaeologists are reported to have found opal-decorated objects in a Kenyan cave, dated to around 4000 BC.
Australia, where opal was identified in 1849 in layers of sandy clay, now supplies most of the world’s opal: Coober Pedy, in South Australia, is its capital, with fields stretching for dozens of kilometers. Opal needs alternating dry and wet periods to form. Since 2008, Ethiopia has become another major producer.
Mineralogically, opal has no crystals: it is a hydrated silica made of tiny spheres that diffract light. Two stones from the same deposit can be completely different, hence its many varieties.
