THE CORRECT ANSWER: The oyster

The oyster is a legendary bivalve mollusc, particularly renowned for its ability to make precious pearls. This fascinating natural phenomenon occurs when a foreign element, such as a grain of sand or a parasite, accidentally gets inside its shell. To protect against this irritation, the mollusk gradually secretes successive layers of mother-of-pearl around the intruder. Over the years, this biological defense process produces a smooth and shiny pearl. Although other bivalve molluscs are able to secrete mother-of-pearl, pearl oysters of the Pteriidae family remain the most famous for the exceptional quality of their gems. These natural pearls have been extremely prized in jewelry since ancient times. Today, the majority of marketed pearls come from pearl farming, a specialized breeding technique developed to artificially stimulate this natural reaction in animals.
