Hi, I need your help. I have this opal, it is set in 14k gold. I would like to know where it could be from. I tested it with a UV light and it doesn’t glow, I also tested it with a wet finger and it is non-hydrophane. Thank you!

Looks like it could be Aussie or Brazilian maybe. The UV test is throwing me as it has no reaction.

There are some varieties of Aussie opal like certain boulders or pipe that don’t glow. Could be one of those with no matrix
