Pearl is the stone of the Moon. Pearl is a tough object produced within the soft tissue of a living shelled mollusk. Just like a mollusk shell, a Pearl is made up of calcium carbonate in minute crystalline form. The ideal Pearl is a smooth lustrous round structure inside the shell of a clam or oyster. Pearl protects native from harmful effects of Moon afflictions. It is more valuable as a jewel. The finest quality natural Pearls have been highly valued as gemstones because of this word Pearl has become the symbol for something very rare, fine, admirable and valuable. The most worthy Pearls occur automatically in the wild, but are extremely rare. These wild Pearls are called natural Pearls. A “Natural Pearl” or “Wild Pearl” is one that appears without any human intervention at all and is very rare.
