Opals

I bought Marielle an opal at a factory outlet place north of the Gold Coast. Did you know that Australia produces about 97% of the world’s opals, mining them in strange sounding places like Coober Pedy and Andamooka? When you visit Australia invariably you will be tempted to buy an opal. To ensure you get value for money you should know what you are buying : http://en.wikipedia.org/wiki/Opal
