I have a large fist sized chunk of Chrysotile (Asbestos). It's really different to see fibers in rock like that. I also have some Galena,
from Galena. My grandmother gave them to me along with other interesting rocks and minerals. She had made for herself a tabletop miniature rock garden and put it under a huge glass dome. It had fabulous looking stones regaled with finely detailed bird and animal figurines in a scenic arrangement.
