What is pearl in the sea?

Pearl is a naturally formed gemstone produced within the soft tissue of living shelled mollusk or oyster. It is commonly found in the sea and is highly prized for its lustrous and iridescent properties. Natural pearls occur in varying sizes, shapes, and colors, with the most sought after being round or near round, with a natural creamy white or golden tone. Pearls can be harvested from various species of oysters found in the Indian Ocean, the Pacific Ocean, and the Gulf of Mexico and are considered one of the oldest known gemstones. Today, cultured pearls, which are produced by inserting a nucleus into an oyster or mollusk, have become more popular than natural pearls due to their affordability, consistency, and ease of production. The pearl trade has been a vital part of the global economic market for centuries, with some of the world's most exquisite pieces fetching millions at auction.
