OPAL: Australian vs. Ethiopian ??

The comparison of Australian and Ethiopian opal is probably one of the most contentious subjects in the world of opal. In this video, I present what I believe to be a relatively accurate comparison of the two opal types. You will likely disagree with some or all of my statements! That is your right ... and perhaps your obligation. My goal is to help people understand the differences so that they can make informed decisions when buying (or selling) opal.
