Agate
Agates are potent stones of harmony and healing, protection, and prosperity. Agate was used by Persian magicians to fend against storms. Other civilizations used it for its ability to quiet the mind, protect against illness, stop thunder and lightning, and heal snake bites and scorpion stings. Agate, when positioned at the head of the bed, was supposed to bring forth happy dreams. Many people nowadays believe that Agate may shield them from harmful energy, and give off a serene, pleased aura.
