How Pearls are Formed

Pearl is the only gem created by a living creature and they have been worn for thousands of years. As an organic gem, pearls are found inside mollusks such as mussels and oysters. Pearls are formed when a bit of sands, tiny stones or other irritants get inside the shell of mollusk, nacre (a lustrous substance) is secreted around the objects in order to protect the mollusk's internal surface. A pearl is formed when this irritant is covered by layers of nacre and the process of building a solid pearl can take up to about 7 to 8 years.
