Akoya pearls are a cultured saltwater pearl farmed mainly in Japan and China, although Vietnam and Australia are also known producers. Small, perfectly round, highly lustrous and seen most commonly in shades of white featuring overtones of rose, cream or silver, the akoya pearls are considered the classic pearl type for necklaces, pendants and earrings. The pearls are cultivated in the pinctada fucata martensii oyster for a period of 12-16 months, on average, and range in size from 2.0-9.5mm.
