Pearl Knowledge Pearls form inside a mollusk which is an invertebrate with a soft body, often protected by a shell such as a clam, oyster or mussel. Any mollusk is capable of producing a pearl, although only those mollusks that have shells lined with nacre produce pearls that are used in the jewellery industry.atural Pearls. Natural pearls, on the other hand, are formed naturally by free-range wild oysters living at sea without any encouragement from humans.
