No. Pearl is an organic substance

Pearl is an organic gemstone. It is a reaction to an irritant within a living pearl-producing mollusk. Mollusks have a soft body often protected by a shell such as calm, mussel, and oyster. Pearls are actually formed when the mollusk produce thousands of nacre. Pearls are commonly used in the jewellery industry.
