Freshwater pearls are formed when a foreign body, such as sand or a shell fragment, penetrates the inside of the mollusc. In an attempt to defend themselves, molluscs cover the foreign body with layers of nacre, which consists of crystallised calcium carbonate. Thus, over time, a pearl forms. Each mollusc and each environment in which it lives can influence the characteristics of the resulting pearl, including its size, shape and colour.
