Origins and deposits of opal
Although it has been mined for over 10,000 years in the Virgin Valley in North America, its discovery is dated to 4000 BC. Indeed, archaeologists have found objects decorated with opal from Ethiopia in a cave in Kenya, they were dated back to that time.
Millions of years later, opal was identified in Australia in 1849. It was then lodged in the layers of sandy clays. Opal production began 50 years later in what is now New South Wales and Queensland.
Today, 75% of opals come from the Coober Pedy fields and these fields extend over 70 kilometers! For opal to form, there must be alternating dry and wet periods, the local climate is more than suitable. The main deposits have therefore mainly been identified on the Oceanic and American continents.
Concerning its aspect, it is quite surprising. Two opal stones can be totally different even though they come from the same deposit. Their iridescent reflections are never the same, which is why there are many kinds of opals.
From the Sanskrit "Upala" meaning "precious stone", the Latin derived the name Opalus, the Greek that of Opallios, and assigned the meaning "to see a change in color".
