Serpentine Skull

Serpentine it 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. 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. You will develop a personal strength and serenity that negativity will simply bounce off of. This is especially important if you are dealing with people who have specific malicious intent towards you and doubly important if those people are at all inclined to use any sort of metaphysical or magical practice against you.
Serpentine is a classic curse-breaking stone if you think that someone is throwing negative psychic energy or even premeditated spells with ill intent your way.
