I’ve seen the trailer but can’t see the show without spending a lot of money.
Australian opals are far superior in quality to any others. Within Australia there are different mines and the characteristics of the opals varies from mine to mine.
I am partial to the vibrant blues, but some opals like those from the Cooper-Pedy mines are mostly white. Apparently reds are considered the most valuable.
Learning skeletons and fossils could be opalised was new to me. Also just rocks.
I had to stop going to the opal websites because I was spending too much money on opals. I just can’t buy every opal I see just because they are pretty.
I love fire opals from Mexico. They can be red, yellow or orange. A large deposit of opal was found in Ethiopia just a couple decades ago, challenging Australia's long dominance of the opal market. Opals are also mined in the USA but I think they are of lesser quality than those which can be found elsewhere. In fact, opals are found all over the world.
