I would say do a scratch test and determine where on the Mohs hardness scale it lays.
To do this, all you would need is a few items and then go from there. The first is get a set of leather gloves. Next get yourself 2 items, the first
is glass, the kind from a broken windshield will do and a piece of quartz. Put on the gloves and select a spot, and then under good light, like
natural light, drag the piece of glass against it. If it does not scratch, repeat with quartz. If the glass scratches it, then there is a good
chance it is glass, but if it scratches easy, then it may be something else. If it does not, try using the quartz. This will give you an idea on how
hard it is, and where to take it. If the quartz does not scratch it, then take it to a mineralogist and have them do an identification of it.
