Pearl Fisheries refers to the industry involved in the cultivation and harvesting of pearls from oysters and other mollusks. This practice can be traced back thousands of years and is primarily concentrated in regions with suitable marine environments. The process includes both natural and cultured methods, with cultured pearls being more common due to their controlled production. The main types of pearls produced in Pearl Fisheries are natural pearls and cultured pearls. Natural pearls form spontaneously in the wild, while cultured pearls are created through human intervention, where a small irritant is introduced into an oyster. Major producers of pearls include countries like Japan, China, and Australia.
