For everyone who has asked - YES THESE ARE REAL!!

A pearl is formed when the mantle tissue is injured by a parasite, an attack of a fish or another event that damages the external fragile rim of the shell of a molluc shell bivalve or gastropod. In response, the mantle tissue of the mollusk secretes nacre into the pearl sac, a cyst that forms during the healing process. Chemically speaking, this is calcium carbonate and a fibrous protein called conchiolin. As the nacre builds up in layers of minute aragonite tablets, it fills the growing pearl sac and eventually forms a pearl. It is a myth that a grain of sand can cause a pearl to form, as nacre will not adhere to inorganic substances.

Natural pearls are those pearls that are formed in nature, more or less by chance.

Cultured pearls, by contrast, are those in which humans take a helping hand. By actually inserting a tissue graft of a donor oyster, a pearl sac forms, and its inner side precipitates calcium carbonate in the form of nacre.
