pearl

4, 000 years ago, a Chinese discovered the first pearl in oysters. The inner of an oyster’ shell is covered with a smooth shiny coating which is called mother-of-pearl. When oyster is opening its shell for eating in the sea-bed, an irritant, such as a grain of sand, goes in suddenly, the oyster immediately takes action by closing its shell, then the sand or irritant gets caught inside the oyster’s shell. To protect the body, oyster coats the irritant with its secrets layers of mother-of-pearl. Finally, the coated grain of sand becomes a pearl.

If the shell of oyster is yellow, then the pearl it produces is mainly in yellow series.
