Pearls are organic gemstones. They are formed when a foreign body becomes trapped inside of the shell of a mollusk. Pearls are a rare occurrence naturally and in previous centuries, thousands of oysters and mussels would have to be opened to find even one. They are now cultivated with the expert help of pearl farmers.
