I like em and think they look cool.
I think I see obsidian. Would love to think those are red emeralds up top, huh? huh? tell me, I gots to know.
You might want to tell where they came from, if you know. That could help in id.
Hard to tell with the red stone, possibly a poor jasper or mineralized granite. The second bit could be a dark agate or a translucent jasper; I lean towards agate.
