Pearls are unique gemstones formed within the soft tissue of living mollusks, primarily oysters and clams. Unlike other gemstones that are mined from the earth, pearls are created through a natural process when an irritant, such as a grain of sand, enters the shell. The mollusk secretes layers of nacre around the irritant, eventually forming a lustrous pearl. These beautiful gems come in various shapes, sizes, and colors, making them highly sought after in the world of jewelry. Cultured pearls, which are farmed with human intervention, dominate the market today. Their timeless elegance and versatility make them a favorite choice for necklaces, earrings, and other accessories.
