Is this black onyx?
Is this community alive? D:

I found this at a friend's house, so I have no solid idea on what it is. I'm pretty sure it's black onyx, but after internet research, I saw that there's several black crystals that look like this when they're tumbled. (The white is from camera flash.)

It does look like Onyx from here. Highly polished, Onxy is a bit less "glass finish shiny" than Obsidian. Can you see any light through it at all?
One way to know is to find a piece that you know is Obsidian of that same size. If this stone weighs more, it's not Obsidian. If it weighs substantially less, like almost nothing, it could be Jet. But from appearance alone, it does seem to be Onyx.

It's definitely heavy enough, and I can't see light through it. Guessing it is indeed onyx.
