    Natural Pearls and Cultured Pearls

    Wild Natural Pearls

    The exact cause that results in the formation of a natural pearl is not fully understood. It was once believed that natural pearls formed in response to a foreign substance (for example, a piece of grit) making its way into the shell of the oyster. Initially it was believed that the oyster coated the invader in layers of nacre as a 'defence mechanism' to protect itself from the substance. While this may be the case in rare examples, research in recent years suggests that natural pearls may actually occur more spontaneously and inexplicably - further adding to their mystique. What we can say is that a natural pearl is one that is formed in nature, without any human intervention. The result is a pearl with a unique combination of size, shape and colour.

    Cultured Pearls

    The growth of cultured pearls requires human intervention and care. Today, most of the mollusks used in the culturing process are raised specifically for that purpose, although some wild mollusks are still collected and used.

    To begin the process, a skilled technician takes mantle tissue from a sacrificed mollusk of the same species and inserts a shell bead along with a small piece of mantle tissue into a host mollusk’s gonad, or several pieces of mantle tissue without beads into a host mollusk’s mantle. If a bead is used, the mantle tissue grows and forms a sac around it and secretes nacre inward and onto the bead to eventually form a cultured pearl. If no bead is used, nacre forms around the individual implanted mantle tissue pieces. Workers tend the mollusks until the cultured pearls are harvested.

    In 1893, Kokichi Mikimoto successfully created the first cultured pearls.
