A natural pearl, which is rather rare, can form over a wide range of time periods, ranging from years to decades. Cultured pearls, which are simply man-made spheres implanted into the appropriate species of shellfish and covered with thin layers of nacre, take a much shorter time, and are harvested after one to five years.

Why are natural pearl expensive?
Natural pearls take years to form, and they are basically an accident. If something as small as a grain of sand gets into the oyster, the muscle/flesh becomes irritated; therefore coating the flesh with a cement covering. This continues for many years until you have a pearl. The chances of finding a natural pearl are quite low, thus the value increases.
