Do you ever find any pearls?

We do find pearls sometimes. Oysters make a pearl when something is bugging them. If they live on a rough beach where they are always tossed around by the waves, they will also have bits of rock tossing around with them. Some of these small rock fragments get inside the oyster's shell when it is open, and irritates their soft flesh. The oyster coats the rock with the same material as it makes its shell with, called nacre, or mother of pearl, and this is a pearl.
