I thought this was pretty interesting. It talks about different stones, what they mean, what sign they're asigned to, and other interesting facts.

Oh this is a great link. Thanks Katie.

you're welcome

I'm a firm believer in the power of stones. I carry them with me for healing purposes, I wear them around my neck to help me feel better throughout the day, and I give them to others who may be having a rough time. Stones are indeed a wonderful healing tool.
