It is also said to be the stone of joy and happiness and in ancient times it was used to ward off evil. It is mined in Brazil, Uruguay, Mexico and the Urals.
Pearls are lustrous and hard organic gems formed within mollusks, mainly in shells, around an original core, which can be either a parasite or a grain of sand. These foreign particles are then coated with layers of calcium carbonate. Pearls are thought to ward off negativism and clarify emotions. In the Revelation of John, pearls adorn the gates of the New Jerusalem.
