Anyone remember seeing something like this stone? The ring is unmarked and has wear. Any input appreciated. What would you guess it’s age. Thank you all.

Is it a stone or is it bugs in acrylic that was popular in the 70’s?

It looks like pinolith…Pinolith pics
But that usually doesn’t have the clear matrix… it might have a resin/acrylic cover over the pinolith.
I see bubbles in the cabochon… which tells me it’s probably foil-backed glass or acrylic. Natural stones rarely ever have bubbles like that. Have your ever heard of Dragon’s Breath in some Fred Harvey era jewelry? Somewhat similar concept to foil-back glass.
Thanks everyone -will update soon.
This is foil-backed purple acrylic. Unmarked, it tested below .925. - not magnetic. Can’t help but notice the stamp work looks cast as well. Would we call this NA, is it sand cast and what era would you say. Thanks again.
