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.
[1913 Webster +PJC]

pearls, being more easily obtained than natural pearls
from wild oysters, are less expensive.
