Glossary

Cultured pearl is a gemstone described as produced through an artificial process that mimics the organic process by which a natural pearl is created. An irritant such as a bead, grain of sand, or piece of mantle tissue is inserted by human intervention into the body of a mollusk, and becomes the nucleus of a pearl once that mollusk secretes nacre to cover the irritation.
