Japanese Akoya Pearls
Japanese Akoya Pearls are cultured saltwater pearls that come primarily from Japan and China. Size ranges from 2mm to 10mm. Common Akoya colors are white, yellow, pink and cream. These color tones are found on the outer edge of the pearl.
Natural freshwater pearls occur in mussels for the same reason that saltwater pearls occur in oysters. Foreign material, usually a sharp object or parasite enters the mussel and cannot be expelled, starting the creation process.
