How do pearls form in oyster shells

How are pearls formed?

Natural pearls are made in oyster shells. The oyster sits on the seabed and keeps its shell closed, but occasionally a grain of sand or two escapes. When this happens, the oyster finds it irritating. It squirts out a few things (like the stuff its shell is made of) to surround the arena and make it less irritating.

The tiny grain of sand gets bigger and bigger the more the material surrounds it and hardens. Eventually it becomes a good sized "thing". The "thing" is a pearl. The pearl can be taken out of the shell and drilled. With cultured pearls, people help.
In fact, on the pearl farms, they inject the grit into the oysters and check if the pearl grows. When it is the right size, it is harvested and drilled. Freshwater pearls are shaped like grains of sand, but saltwater pearls and cultured pearls are round.
