Very cool. Is it a specific kind that is supposed to help keep one grounded? Or just any crystal would work?
I was given one once during a time I was very unstable. It was supposed to promote balance and healing. I carried it with me for a long time. I'm not sure if it really helped, or it was a placebo thing, but I still dig it out when I get more dissociative. Can't remember the name of it though.
