Interesting - that is what I believed would happen with my stones, but they register as more yellowish green in CFL lighting than in sunlight. Go figure...
Anyway, I love your stone! Sometimes I think Gene could take coke bottle glass and make it look beautiful!
It would make a gorgeous pendant, but I really want to look at it, and the movement will show the sparkle, so I'm thinking ring. That's as far as I've gotten, though.
