Hi. Does anyone know what this is?

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.
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.
I would definitely subject the clear portion to a scratch test with a knife blade. If it can be scratched with a pocket knife blade it is not quartz. It just looks a little too rounded to be quartz to me. (If the quartz is that rounded, then any softer host rock should’ve been worn away.) If it can be scratched with a knife blade, my guess would be zeolite. The host rock could then be basalt. If it cannot be scratched with a knife blade, then it probably is quartz. Do you mind saying the general region where you obtained it?
I think that solves the question, it's a tar or asphalt of some type. The quartz, I'm pretty sure, was part of the mix.
