A cultured pearl is a pearl created by a mussel farmer or oyster farmer under controlled conditions. Cultured pearls can be farmed using two very different groups of bivalve mollusk: the freshwater river mussels, and the saltwater pearl oysters.

It's safe to use warm, soapy water for occasional, thorough cleaning. If the pearls are strung, be sure the string is completely dry before wearing. For routine care, it's best to wipe cultured pearls with a very soft, clean cloth after each wearing.

Pearl rings are best used for occasional wear.
