Pearl cultivation is the process of farming pearls from oysters or mussels. It involves inserting a small bead or piece of tissue into the mollusk, which then secretes layers of nacre around the irritant, forming a pearl over time. This method allows for the production of pearls in a controlled environment, ensuring quality and consistency. The cultivation process typically takes several years, depending on the type of pearl desired. Once harvested, pearls are cleaned and sorted based on size, shape, and luster. Cultivated pearls can be found in various colors and are often used in jewelry, making them popular among consumers.
