Yay! Pretty rocks! When I was a child, my mother would drag me to crafts fairs and everytime, there was someone with some table of shiny rocks like this. I wonder if somehow they were late 90s new agers, but when I was a kid, I didn't care. I paid my fifty cents, and walked about proudly with my selection in its mini zip loc bag.
I really like these smooth tumbled rocks, since you can play with them, and it's really relaxing. I also like to hear the powers people attribute to these stones. I like myths of all kinds, for some reason.
