From The Collaborative International Dictionary of English v.0.48:

Pearl \Pearl\, 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.

   Note: 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.

   2. Hence, figuratively, something resembling a pearl;

      usually made from mother-of-pearl, and additional layers

      from wild oysters, are less expensive.
