The most commonly can be divided into natural pearls, cultured pearls and freshwater pearls three categories. Natural pearls - It is a product form pearl shell mussel and a shell with nacre can produce pearls. When the shells open, the sand or micro-organisms liked objects have the opportunity to enter the body by stimulating the mussels, it will secrete layers of nacre to surround the invaders, after years of secretion, and the sand is surrounded by a layer of secreted material, resulting in a pearl. Cultured pearls – the formation of cultured pearls is very similar to natural pearls. The only difference is that the clam is not a foreign substance but the farmers deliberately put a round beads in vivo nuclear as the secretion of nacre being stabbed, forming a bright and cultured pearls. Process of cultured pearls, the farmers usually picked up the shell, and then open it with tools, and cut a small wound of the nuclear, and then put the bead core into the nuclear shell, add a small amount of anti-inflammatory drugs, then put it back to the sea; then check the shell after six weeks, the healthy shells will continue farming in the sea, they can develop as cultured pearls after three years. In general, cultured pearls can be divided into South Sea pearls, and Tahitian colors pearls. At present, the expensive and high-quality pearls are Tahitian pearls and South Sea pearl. South Sea Pearl - are produced in the South Pacific Ocean (i.e., the ocean in northwest Australia, Philippines and Indonesia), White Butterfly Shell is a very rare spices men and vulnerable creatures, must be growth in a stable, good and pollution free environment, but it is also the world's largest oyster to cultivated pearl, the average size of South Sea pearl is larger than the fresh water pearls, or cultured pearls. Therefore, the worth of South Sea Pearl is also become more expensive. The value of South Sea pearls are evaluated depends on the sizes, colors, shapes, luster and clarity. The big, round and pink colored eye-catching is the most precious; some of the size can be rarely from eighteen to twenty millimeters. There are vary shape of South Sea pearls, round, oval, circular, button-shaped, even irregular shape, more rounded shape the more rare. Tahitian Natural Pearl - is different to South Sea pearls and beads from Japan, and can be described as a premium precious. Because the pearl itself is a precious black mussel dish (a limited growth only in natural, pollution-free waters of the rare Polynesian mussels) farming out in different levels grade of grayish color with a different Symphony, which make it more and different to other pearls. In addition with their breeding environment, and the process requires are very strict, every hundred of black disc beads mussel colonization, will only have fifty out successfully cultivated as pearls, in which there are only five perfectly pearls existed and therefore each of them is priceless. Freshwater cultured pearls - is a nuclear-free cultured pearls beads, are productive in river or lake. Similar surgical procedures as cultured pearls, but their sizes are smaller. An oyster can farming up to hundreds of freshwater pearls, the price of freshwater pearls are often cheaper than sea water cultured pearls.
