This is the caller of Saint Germain, it is 14k white gold with one diamond and one pearl. It came to be when Saint Germain stood physically in front of a woman named Marie Dujon. He left her with the pearl and it was set into the pendant. You use it as you would a pendulum, calling on Saint Germain for guidance. It really swings fast and takes no time to get it going once you begin to use it and have called upon Saint Germain for his guidance. It never fails to work and can be worn and taken off to use.
