Hello all- My grandmother was a rockhound and left me her collection when she passed away years ago. I know what everything is she gave me except this clear mint or blue green stone that I believed was beryl until I recently took it to a local gemologist
who tested it and said it wasn't beryl but also couldn't identify for me?
The test results were 6.5 +/- hardness and 1.775 on refractive index and I've been looking up everything online but found nothing real close except possibly garnet?
Any help would be appreciated.
