Difference among natural and cultured pearls
Natural pearls are shaped in the wild, within the oysters in extensive oceans, whilst an irritant like a grain of sand enters the mollusk. The oyster secretes a protective layer known as nacre across the irritant. The oyster continues to form layers over layers of nacre over its lifetime, which in the long run becomes a pearl. This process occurs over a length of numerous years. For instance, an 8-9mm pearl may take as long as 5-6 years to form that size and depth. For this reason, herbal pearls are rare and really steeply-priced.
Cultured pearls, alternatively, are grown inner mussels which are cultured in a pearl farm, wherein the farmer regularly introduces the irritants so he can alter the intensity and luster of resulting pearls and make the manner greater fast.

Saltwater cultured pearls are grown in oysters that stay in the ocean, usually in blanketed lagoons, just like the South Sea pearls and Tahitian pearls.
Freshwater cultured pearls are formed in freshwater mussels that live in freshwater our bodies like lakes and ponds. Advancement in culturing techniques during the last ten years have made freshwater pearls very close in first-rate to the saltwater pearls and plenty much less high priced.
