This is a beautiful Tetragrammaton sterling silver pentacle pendant. Pentacles have been used and worn as powerful symbols of protection for thousands of years. It's meaning has roots in philosophy, religion, alchemy, magic and mysticism. The five points of the pentacle can represent the four elements of fire, water, earth, and air. The fifth represents spirit. The Tetragrammaton figures in magical formulae from the time of the Gnostics, and on amulets. Many a medieval miracle-worker was supposed to derive his competence from his knowledge of the Tetragrammaton.
