I always thought Thunder Eggs were beautiful. I hadn’t seen one in person until recently but I’ve loved looking at the pictures of cut pieces online over the years. I haven’t seen too many sphered as I imagine they look best sliced in half, but I thought I’d give it a shot anyway. I bought a couple larger ones (about two pounds each) from Oregon. I don’t know a ton more about them than just that. I think they turned out pretty nice. They ended up looking like little planets to me. What do you think?
I also had a couple sand stones and an unfinished ugly conglomerate stone I had found on Lake Michigan. I decided to finish those and they are pictured also.
