In the early 1990s, a new opal deposit was discovered in Africa. This new material, found in Ethiopia, had a yellow to brown base color and was fairly unstable. However, in 2008 a new deposit was found in northern Ethiopia producing white-base to semi-crystal, high-grade material. This new discovery gave an alternative to the well-known Australian opal on the open market. Being sold at competitive and affordable pricing, consumers now had a new choice in opal.
