A couple of my opal videos
John Robinson:
I thought there might be a few interested in seeing these videos(?)
I could be wrong...

Very nice! Were those both Spencers? Great pattern. Are those doublets?
John Robinson:
Yes, they are both under glass cabochons. The smaller one (I think) is Ethiopian, but when I bought the rough it was just labeled ‘Fire Opal’ rough and the seller did not know it’s origins. I suppose I should put in water to see if it changes color - but I really do not want it to change..lol
gemfeller:
Just wet a finger and see if the opal rough tends to stick to it. That's the usual test to determine if opal is Welo (Ethiopian). Welo opal is hydrophane, meaning it's "thirsty" and easily absorbs water. This test won't harm your opal.
irockhound:
OMG Rick! Great to see you on my friend! Rick is right on the Welo, I have cut them and watch the fire disappear if I am cutting for a long time. Never had one not regain its color completely. Opal from Red Rock Canyon in California does the same thing.
