That's an odd one. The light mineral on the inside looks like Quartz. that black stuff is odd. Can you scratch it off with a knife? It just doesn't look like a natural coating from the picture.

Interesting.
Wondering what it would look like with a laser beam hitting it.
I do that looking for rocks on the beach along with my UV spot light.

Does no look like black quartz to me. It appears to be some sort of coating. That's why I asked for them to scratch it.
