A Guide to Pearls
What is a cultured pearl?
Cultured pearls result from a small irritant being implanted into living oysters (Akoya and South Sea pearls) or mussels (Freshwater pearls). The oysters or mussels secrete a substance called "nacre" which bonds to the irritant. The layers of nacre form the pearl.

LUSTER - The glow of the pearl and it's brilliance to the human eye. The longer the pearl is left in the oyster, the thicker the nacre, which results in a higher luster.
SHAPE - The more symmetrical the pearl is, the better the quality.
SURFACE - The fewer natural markings on the pearl's surface, the better the quality.
SIZE - Pearls are measured in millimeters. The larger the pearl, the more valuable.
