Pearls, a natural gem, is considered a sign of wealth and good taste. It's the only natural occurring gem created by a living creature. And, they never go out of style. They have been worn for thousands of years. They can be worn as a: single strand, multi strand, twisted multi strand, as a pendant, or within a pattern of other types of beads. Pearls are classified as either natural or cultured.
Natural pearls are harvested from saltwater or freshwater. They occur naturally without human intervention. A mollusk secretes layers of nacre around an irritant, that has entered naturally, to protect itself. This nacre covered irritant becomes the nucleus of a pearl. The longer the irritant is inside the mollusk the larger the pearl will be. An irritant can be a small sea animal, snails, worms, debris, shell bits, clay, or on the rare occasion a grain of sand. A natural pearl is very rare and extremely expensive. Natural pearl color is usually white. And, its shape might be round or baroque.
Cultured pearls are harvested from saltwater and freshwater, as well. The difference from a natural pearl is that instead of the irritant entering the mollusk naturally, human intervention takes over and skilled hands will place an irritant inside the shell. The mollusk is usually a oyster or mussel. And, very good care is taken to cultivate the pearl until it's ready to be harvested.
For cultured freshwater pearls, the irritant introduced to the mollusk that will eventually form the pearl nucleus is a piece of shaped mantle from another mollusk. A single mussel might grow 10-20 pearls, therefore, this method is inexpensive.
Cultured saltwater pearls have a shell bead nucleus with mantle tissue introduced as an irritant. When the pearls are harvested in this instance, the oyster dies. The rate of pearl production for cultured saltwater pearls are slow. Only 1 in 5 pearls from a given oyster is salable, hence a higher price. Cultured pearls very in size, shape and color. Naturally occurring colors are white, pink, lilac, cream, grey, black or gold.
