Serpentine is one of the most historically used stones for detecting evil and protecting against both bad luck and intentional malicious behaviour – even against dark magic. 

Serpentine stones are excellent for developing a distinct inner peace that makes you untouchable by negative energy. Instead of this stone “sucking up” the bad energy from around you like a magnet, it will harden your psychic “shell” and make it impossible for that bad energy to permeate.
