How do Pearls formed from an oyster? It is truly a very interesting question. Unlike most precious gems are formed in the ground, surrounded by rocks, Pearls are the only gemstone created inside a living creature. Actually pearls can be created from oysters, clams and mussels. However, most pearls we can find nowadays are mainly produced by oysters no matter freshwater pearls or saltwater pearls.
To help you better understanding how pearls make from, let's take a look at the structure of the oyster as below first:
Mantle is directly related to the formation of pearls. Mantel is an organ of oyster shell produced by minerals in oyster food. Nacre lines the inside of the shell.
As for natural pearls, in order to protect themselves, oysters naturally wrap stimulants with nacre, forming pearls in the long run.
Cultured pearls are artificially placed between the mantle and the shell. Open the oyster with the machine, cut a small slit in the shell tissue, and insert the stimulant under the coat. Note: the irritants here are not plastic. The mantle of other mother oysters is inserted into the Pearl cultured in freshwater.
Meanwhile, according to the research result from Rene Reaumur, a French natural scientist in 1717, foreign bodies enter the animal body or the animal itself produces parasites and other lesions. To protect itself, the animal secretes calcium carbonate to surround the foreign bodies or lesions and form stone-like objects. This result proved that pearls are the product of oysters protecting themselves.
