Does anyone else use gems?

I worded my post wrong, and was very tired when I wrote it. I didn't exactly mean light refraction, it was just the first thing to pop up into my head about how to relate to energy. I really honestly don't know how scientifically a person reacting or 'healing' because of stones, can be shown, nor do I plan to show proof. I suppose I just figured it could be physically possible to show, and didn't really do too much research on it, sorta like the idea that one day we'll colonize the moon. If you don't get what I mean, I mean to say that I really have no scientific experience to back it up, so it may as well be me just being weird.

It's all groovy.
