Pearls: The Gem Of The Sea
Pearl quality can vary dramatically, and just like other gemstones, only a tiny percentage are considered beautiful enough for use in jewelry. Characteristics that contribute to the value of a pearl are luster and nacre thickness, surface, shape, color and size.
Natural Pearls
A natural pearl is created organically when an irritant accidentally finds itself inside the oyster's soft tissue muscle. Irritants, such as seawater, sand, or dust, activate the oyster's defense mechanisms, causing it to produce layers of secretion. The secretion, or nacre, slowly develops into a natural pearl. Because of this, Natural Pearls are much rare and more valuable.
Cultured Pearls
Most pearls on the market today are cultured. A cultured pearl is a natural pearl produced by an oyster or mollusk, but with human assistance. The survival rates of Cultured Pearls are much higher because they are created in controlled environments. Pearl farmers are then able to produce high-quality, authentic pearls at a higher rate than what can be obtained by oyster divers. The two main types of cultured pearls are freshwater and saltwater pearls.
