Ethiopian Opal: The Volcanic Newcomer
Origin and Geology
Ethiopian opals were largely unknown to the global gem trade until deposits were discovered in the Wollo Province of northern Ethiopia in the early 2000s. The most significant commercial discoveries came from the Wegel Tena area around 2008, rapidly making Ethiopia one of the world's most important opal-producing regions.
Unlike Australian opals, Ethiopian opals are formed through volcanic activity. Silica-rich water moved through volcanic rock and hardened into opal within cavities and cracks in the stone. This volcanic origin gives Ethiopian opals a more porous, open structure — and a characteristic that sets them apart from almost every other gemstone: hydrophane behavior.
