cultured pearl

A pearl is formed when a small irritant or parasite penetrates and lodges in the mantle tissue of a mollusk. In response, a substance called nacre is secreted, and the creation of a pearl begins. Nacre is a combination of crystalline and organic substances. The nacre builds up in layers, as it surrounds the irritant to protect the mollusk, and after a few years, this build up of nacre forms a pearl.

Nearly all pearls sold today are cultured pearls. Cultured pearls are a product of pearl farmers helping nature. Several inventors at the beginning of the 20th century discovered techniques of pearl cultivation.

Cultured pearls can be from saltwater or freshwater mollusks. Pearl farmers introduce a shell bead into the oyster or mussel and the mollusk deposits layers of nacre around the bead. Many people use the term cultured pearls to refer only to pearls produced from saltwater oysters.
