A pearl is a hard, iridescent object produced within the soft tissue of a living, shelled mollusc. A pearl is made up of calcium carbonate and layers of animal membrane (conchiolin). The ideal pearl is perfectly round and smooth, but many other shapes of pearls (baroque pearls) occur.

The most valuable pearls appear in the wild (natural pearls), but they are rare. Since the early twentieth century cultured or farmed pearls from pearl oysters and freshwater mussels have made up the majority of pearls sold. Pearls are often used for jewellery, but in the past were also stitched onto garments in decorative patterns (pearl embroidery). Imitation pearls made from a wide variety of materials such as glass, metal, plastic, shell covered plaster and ground up shells are used for inexpensive jewellery.
