How do oysters make pearls

Hello folks. I have Very good information to share with you all. Do you know Oysters make pearl within them? If you don’t know here is the process. Oysters belong to the class of mollusk because of their double shells. Oysters have a soft and sensitive body inside their hard shells. When a grain of sand gets inside the shell of the oyster, it starts covering the grain with layers of hard smooth substances called nacre. This is done to reduce the irritation caused by the grain of sand to the sensitive body of the oyster. A beautiful white silky pearl is formed when many layers of the substances are produced by it. To get more pearls people deliberately started inducing a grain of sand or a bead which resulted in cultured pearls. They are same as the natural pearls only difference being the process of producing the pearls is artificially or naturally induced The color of the pearl differs mainly because of the type of the mollusk and the environment. The colors can be found from black to white, cream, gray, blue yellow, lavender, mauve and green. There are different types of pearls like fresh water pearls, ocean pearls and etc.
