Where did you get them? They seem to be very pure. Did you buy them? If you found them, where did you find them? I think they are beautiful specimens.

I would not speculate without more info.

Can you scratch the spacimens with your fingernail, a regular nail, a piece of quartz?

I can see they are translucent. If you shine a light on them, do either one of them flouresce, (glow in the dark)?

The inability to scratch it says it is pretty hard. I do not see a single crack or fissure in either rock. The way hard rocks break off is called conchoidal fracture. It forms flakes like the flint knappers and pieces chip off. If a s,all piece could be cut off, you could streak test it, or, there are other tests. The easiest way is to take them along with you to a rock shop.

Looks like a glass

Agreed. At first glance I thought fluorite, but the conchoidal fracture and lack of cleavage would indicate a liklihood of glass.
