Akoya pearls are a type of cultured pearl primarily produced in Japan and China. They are formed by the Pinctada fucata oyster and are known for their round shape, high luster, and a wide range of colors, including white, cream, and pink. Akoya pearls typically measure between 2mm and 10mm in diameter, making them a popular choice for jewelry. These pearls are often used in necklaces, earrings, and bracelets, celebrated for their classic elegance. The cultivation process involves inserting a small bead into the oyster, which then secretes layers of nacre around it, resulting in the beautiful pearls that are highly sought after in the jewelry market.
