Mother of Pearl

Mother of Pearl

Mother of pearl is the common name for iridescent nacre , a blend of minerals that are secreted by oysters and other mollusks and deposited inside their shells, coating and protecting them from parasites and foreign objects. Nacre is the same substance that is deposited around an object that becomes lodged in the mollusk--either naturally or inserted by humans--to become a pearl. Jewelry made from mother of pearl falls in the group referred to as organic jewelry -- jewelry that originates from a living creature, plant or organism.
