Why are pearls so special?

Pearls are so special because they are rare in nature. They form only when something gets inside an oyster or mussel and causes irritation. The mollusk then secretes substances similar to those found on its shell. These harden around the foreign body to create a pearl. Only about one out of every 10,000 wild oysters will ever make a single pearl, and the vast majority of the pearls that occur naturally are too small to use in jewelry.
