Akoyagyöngy

Akoyagyöngy, commonly known as the Akoya pearl, is a cultured pearl produced by the saltwater oyster Pinctada fucata martensii. The most highly regarded Akoya pearls originate from Japan and China, where the oyster is raised in controlled marine environments. Akoya pearls have long been central to the development of modern cultured pearl production, with the technique refined in the early 20th century.

Akoya pearls are created by implanting a small bead nucleus and a piece of mantle tissue into the oyster, which then secretes nacre around the nucleus to form the pearl. After several months to a few years, the oysters are opened and the pearls are harvested. They are typically small, ranging from about 2 to 10 millimeters in diameter, and are valued for their high luster and smooth nacre. Shapes are usually round to near-round, with surface quality varying by individual pearl. Color is most commonly white or cream, often with pink or silver overtones.

In grading, Akoya pearls are assessed by luster, surface quality, shape, size, and color. They are commonly marketed in grades such as A, AA, and AAA, with AAA representing the highest quality. Many Akoya pearls undergo surface treatments, such as bleaching to enhance whiteness, and some are dyed to produce alternative colors for specific markets.

Market and use: Akoya pearls remain popular in fine jewelry, especially earrings, pendants, and classic necklaces. Prices depend on luster, size, shape, and surface quality, with supply influenced by production from both Japan and China.
