Akoya cultured pearls are produced in salt-water mollusks in Japan and China. They were the first type of pearl to be cultured, back in the 1920s, and they remain the most popular and classic choice for pearl jewelry. Akoya cultured pearls are prized for their smoothness, roundness, and gorgeous deep luster, and for their lovely color--usually white with rose overtones. Though they may look similar to freshwater cultured pearls, when the two are placed side-by-side, the Akoya pearl's superior qualities are clear.
