n. [ OE. perle, F. perle, LL. perla, perula, probably fr. (assumed) L. pirulo, dim. of L. pirum a pear. See Pear, and cf. Purl to mantle. ] 1. (Zool.) A shelly concretion, usually rounded, and having a brilliant luster, with varying tints, found in the mantle, or between the mantle and shell, of certain bivalve mollusks, especially in the pearl oysters and river mussels, and sometimes in certain univalves. It is usually due to a secretion of shelly substance around some irritating foreign particle. Its substance is the same as nacre, or mother-of-pearl. Pearls which are round, or nearly round, and of fine luster, are highly esteemed as jewels, and at one time compared in value with the precious stones. Since development of cultured pearls, the relative value has diminished somewhat, though the best pearls are still expensive, and natural pearls even more so. Artificial pearls may be made of various materials, including material similar to that of natural pearls; these are less expensive than natural or cultured pearls. See cultured pearl, below.
