NacreNacre, also referred to as mother-of-pearl, is the iridescent substance that lines the internal layer of a mollusk shell as well as what forms around an irritant (such as a mother-of-pearl bead inserted into a mollusk by a pearl farmer) to create a pearl. Nacre itself is the layers of calcium carbonate and conchiolin that form over the irritant. Nacre is extremely important because it determines the longevity of a pearl. A pearl with a thin nacre will not last as long as a pearl with a thick nacre. |
