The pearl industry involves the cultivation and harvesting of pearls, which are precious gemstones formed inside mollusks, primarily oysters. Pearls can be natural or cultured, with cultured pearls being more common due to advancements in aquaculture techniques. The industry is significant in countries like Japan, China, and Australia, where specific species of oysters are farmed for their pearls. Pearls are valued for their beauty and luster, making them popular in jewelry and fashion. The pearl market fluctuates based on demand, quality, and the rarity of specific types, such as Akoya, Tahitian, and South Sea pearls. Sustainable practices are increasingly emphasized to protect marine ecosystems.
