I purchased this to a few months ago to wear on a long chain I have, and knew it wasn’t Native American. The seller said it was turquoise. It doesn’t really look like any turquoise I am used to seeing, but it does look like real stone. I tested the back with acetone on a q-tip and no color came off.
My guess is adventurine. It’s a form of microcrystalline quartz, I believe. This is a common color. Reminds me of jade, a bit.
Possibly, but I have a green adventurine cab an it’s much more “quartzy”. This is pretty dull and flat looking.
The curled motifs in metal look very like Chinese/Tibetan/Asian cloud designs…And the overall feel of the metalwork (weight/thickness) as well. Could be the turquoise is, as well… (Just my limited-knowledge two-cents worth…)
