How Are Oyster Pearls Formed. Most pearls are produced by oysters in both freshwater and saltwater environments. The pearl sac then secretes calcium carbonate and conchiolin. But beyond this ecological role, oysters possess a mesmerizing ability to transform tiny irritants into gleaming treasures: To understand how pearls are formed in oysters, you must first understand an oyster's basic anatomy. Pearls are formed inside oysters when an irritant, such as a grain of sand or a piece of shell, gets trapped inside the oyster’s soft. The shell's valves are held together by an elastic ligament. To the oyster, this foreign object is discomforting. Despite their iridescent colors and smooth shapes, pearls are actually made of the exact same material as the craggy shell that surrounds them. Imagine a fine grain of sand, or perhaps a minuscule parasite, inadvertently finding its way inside an oyster's shell. Oysters are bivalves, which means that its shell is made of two parts, or valves. Cells from the mantle of the oyster form a pearl sac around the irritation. Pearls are made by marine oysters and freshwater mussels as a natural defence against an irritant such as a parasite entering. Pearls are formed when an irritant gets trapped inside a mollusk, and the animal protects itself by building smooth layers of mineral and protein — together called nacre — around it.
