I'm trying to identify this stone. It looks like abatite or paraiba tormaline. It has a density of 2.77 and it can be scratched with a knife. Could it be scapolite?
You can see I cut a small part of stone and in the picture where it's blue it was because it was under black light.
could it be glass of some type ? I have plenty of stones and crystals but never seen one so uniformly transparent, reminds me of a thick bullet proof smoked glass..
But then again i am no specialist
