The pearl industry involves the cultivation and harvesting of pearls, which are precious gemstones formed inside mollusks, primarily oysters and mussels. 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 large-scale pearl farms operate. Pearls are valued for their beauty and luster, making them popular in jewelry. The industry also faces challenges, such as environmental changes and overfishing, which can impact mollusk populations. Sustainable practices are increasingly important to ensure the long-term viability of the pearl industry.
