Why is it that pearls are perfectly round? Does it always happen that way?

Pearls are not perfectly round. Every pearl contains some imperfection. From what I have read, nearly round pearls are relatively rare, making them more valuable. They are graded according to shape, size, and color. I saw a very interesting article on pearls in a recent National Geographic (probably one of the 1993 issues) if you want to research this topic further.
