The pearl is an ancient and very precious gemstone that can be grown in both fresh and salt water and is also known as the "Queen of Gems". It takes its name because it is a rare, pure and healing stone.
Pearls can be grown in two ways: point- on, in which a grain of sand enters the shell and to protect itself, surrounds the body with layers of nacre, forming the pearl. Or cultivated, where a foreign body, which can be a part of another mollusc is injected into the oyster and then the mollusc takes care of cobing it with several layers of nacre, until it forms the pearl.
In China pearl powder is used in the cure of various diseases. In India it is used as modern therapy for its revitalizing and aphrodisiac properties. Among the Greeks the symbology is completely distinct, the pearl is considered the symbol of love and marriage.
