Saltwater pearls from the Akoya oyster (Pinctada fucata martensii) are usually cultured. The sizes of Akoya pearls range from 2-10 mm. These pearls are typically roundish. The main colors are white, silver, rose pink and pink with cream, gold, green and blue overtones.
Even though they are often called Japanese pearls they can also be found in oysters outside Japan. In fact China has become the major producer of Akoya pearls measured less than 7mm in size. Currently, most Akoya pearls over 7 mm are cultured in Japan. |
