Greetings,

I have received several stones and crystals from my old grandpa. Most of the stones and crystals we have identified but there is one crystal we can't figure out what it is. I have googled a lot but could not find a crystal that would match. The ones that's come near are dioptase and epidote but we are not sure.

Any help is appricated.

Regards,
Ruben

Ruben, Was your grandpa from Spain? If so, I suspect that piece comes from Los Serranos quarry in Alicante: https://www.mindat.org/loc-3101.html
