When you check their luster, Akoya pearls have beautiful luster compared to freshwater pearls. Another differentiating feature of the two is that the nacre layer of freshwater pearls is very thick compared to that of Akoya pearls.
Unlike Akoya pearls that are mostly cultivated in China or Japan, the cultivation of freshwater pearls is usually in ponds or lakes. Also, unlike Akoya pearls that have a white color with a blend of ivory, rose, and silver, freshwater pearls come in different colors lilac, white and peach. Akoya pearls are perfectly round in shape, whereas the roundness of freshwater pearls is not as perfect as that of Akoya pearls. In terms of price, freshwater pearls are not as expensive as Akoya pearls, and this is because of the certain features of Akoya pearls. However, Akoya pearls are not as durable as freshwater pearls.
