PEARL is often considered a gemstone, although it is not a mineral. Rather, pearl is a composite of the mineral Aragonite (Calcium Carbonate) and the organic compound conchiolin (a protein). The combination is called nacre, or mother-of-pearl. In some cases, there is a mixture of the mineral calcite (another mineral composed of Calcium Carbonate). In pearl oysters and freshwater pearl mussels, nacre forms the inner lining of the shell. In most other mollusks the shell has an appearance more like porcelain and lacks the luster and iridescence of mother-of-pearl.
