Jet: protection, anti-nightmare, luck, divination, health
Jet is fossilized wood. It was said to absorb a piece of the wearers soul for protection. In ancient Greece, the priestesses of the goddess, Cybele, used it to curry her favor. Jet was found in pre-historic graves as burial gifts for fortune and to guard the departing spirit, so it passed on to the next life safely. It was burned by sea witches for divination and other purposes. In the Middle Ages, it was carved into the shape of a beetle for protection.
Jet absorbs negativity, removing it from the wearer and their environment. It is used to guard against nightmares and is placed under the pillow to ward off these bad dreams. Jet also increases psychic abilities (such as in divination) and medium abilities in contacting and conversing with the dead. Jet is also said to keep proper energy flow in healing spells and rituals.
