Opal

At the moment opal is one of the most wanted & loved and therefore most expensive gemstones in the world. No opal is as sought after as the Australian opals from Lightningridge, Coober peddy and some other areas in Australia. There are also a lot of different types of these Australian opals, but the most expensive is the Austalian black opal. However, in addition to Australian opals, there are also many other types of opal. Such as honduras opal, Mexican fire opal and Ethiopian opal. These just mentioned species also belong to a somewhat more expensive category of opal and are just below Australian opals in terms of prices. The cheaper opals are opals that often lack the color effect, such as yellow opal from Tanzania, green opal from Madagascar and Andean opal from South America.
