A pearl is a natural gem created by a living organism. When a foreign object is introduced into a mussel or oyster the animal coats the irritant with a substance called nacre, the same material with which it builds it's shell. Over time, the layers of nacre build up to form the pearl. The longer the irritant remains in the mollusc, the more layers of nacre and (usually), the better the pearl.

A grain of sand accidently falls inside the oyster and the irritation from the sand causes the oyster to coat it with layers of aragonite, conchiolin, and nacre, which makes them shiny. The larger the grain of sand, the larger the pearl. Most pearls today are made by humans by purposely injecting a bead into the oyster.

It is a lot like when you get a scar over a wound or a callous on part of your body that gets a lot of wear (like heels or hands). The oyster is protecting itself from a foreign object by isolating it, by forming the pearl.

Well it basically irriates them so they put a protective and smooth coating on it so that it does bother them as much. Over time there is more and more until its a beautiful, white pearl
