Hello,
I bought these to stones in a lot on auction. I have not been able to get them to a gemologist due to Covid. I have had some suggestions that they may be Actinolite cat’s eye. I have been told that they are not chrysoberyl because of the way the back of the stones look and are probably glass. I have checked under the loupe and there are no visible side dots pointing to fibre optic glass. Does anyone have any ideas? :)

Get them tested. I see no reason looking at the back of the stone that rules out Chrysoberyl.

I was thinking the same, sure look like crysoberyl. Covid shouldn't be stopping you now, a few simple tests by a good gemologist will answer your questions very quickly.

View them, with magnification, perpendicular to top of the stone. Fiber optic glass will have a diagnostic honey-comb like profile.

Thank you for everyone’s feedback! Checked for honeycomb on top and sides of both stones- no honeycomb or dots. :)

The effect is only visible from the sides, not the top.
That being said, I think a few gemological tests are in order.
I'd start with a spot RI and Specific Gravity.
