WHAT IS A CULTURED PEARL?

 

Pearls are made of the same material as the mother-of-pearl lining in the shell of the oyster. The body of the oyster is very tender, so to protect itself the oyster secretes this mother-of-pearl lining to provide a smooth surface against the body. When an irritating object, such as a grain of sand, manages to get inside the oyster’s shell, the oyster coats it with layer after layer of mother-of-pearl and this becomes a pearl. When this happens naturally, the petal may be perfectly shaped. But man has found a way to help the oyster in the making of pearls. A grain of sand is inserted between the shell and the outer skin of the oyster. After two or three years, when these shells are taken from water and opened, a pearl is found inside. These are called ‘cultured’ pearls, and are usually not perfectly shaped.
