Peridot. Thought to drive away the evil spirits at night. This was because of how it reflected the candle light back before electricity.

From Supat Pakistan which is considered the best quality in the world.

Beautifully cut stone with many facets to make it really lively. Fully reflective with no window. True master cut stone. High end gem quality. You can see this for yourself if you compare with other listings and compare prices with this. I try to be honorable in my posts and make customers happy with honest dealings. I believe I stand out above most others for this and you can check and see for yourself. Please rad my feedback and listen to what others say about me in my reviews. If I don't like the stone myself I'm not interested in offering it to you or anyone else as for me that would be somewhat embarrassing.
