For centuries, pearls have been a symbol of beauty and purity. Today, they are regarded as both classic and contemporary, coming in many more fashionable styles than your grandmother’s traditional strand of pearls.
Learning about types of pearls is important when adding items to your jewelry collection.
Pearls, natural or cultured, are formed when a mollusk produces layers of nacre (pronounced NAY-kur) around some type of irritant inside its shell. In natural pearls, the irritant may be another organism from the water. In cultured pearls, a mother-of-pearl bead or a piece of tissue is inserted (by man) into the mollusk to start the process.
For both, the quality of the nacre dictates the quality of the luster, or shine of the pearl, which is very important to its beauty and its value. The surface of the pearl should be smooth and free of marks while the overall shape could be round, oval, pear-shaped, or even misshapen. Misshapen pearls are called baroque pearls.
Necklaces can also be classified as uniform (where all pearls are about the same size) or graduated (pearls change uniformly from ends to center).
Natural pearls are extremely rare. Historically, many were found in the Persian Gulf; unfortunately, today, most have already been harvested. You may be able to purchase small, natural pearls, but they will be costly.
Cultured pearls are grown in pearl farms. The mollusks are raised until they are old enough to accept the mother-of-pearl bead nucleus. Through a delicate surgical procedure, the technician implants the bead and then the mollusks are returned to the water and cared for while the pearl forms.
