Pearl producers harvest akoya pearls in Pinctada genus’s bivalve mollusk. The primary species that are used in its cultivation process are the Pinctada chemnizti and the Pinctada fucata (usually the sub-species martensii). Pinctada fucata martensi especially is the native of Japans coastal waves. Pinctada chemnitzi tend to be more specific in the Gulf of Tonkin and commonly found in the China’s coastal region.

In the present day and time, almost more than half of the akoya pearl producers are found in China and Japan alone and the two species go through a hybridization process too.

Cultured Akoya Pearls Production

In the last century, it has been observed that Japan has remained a strong contender and has cultivated akoya pearls in humongous quantity. Japanese akoya pearls is well known for its rich and classic quality, just as what they were about 100 years back. They are cultured in the very same way in which it was first done by William Saville-Kent and is used by Kokichi Mikimoto—the very same nucleus insertion technique which is used today. There are so many pearl shops like https://pearlsonly.ca/ which have a good pearl jewelry collection.

The Standard Traits of Akoya Pearls

The oysters of Akoya pearl be it Chinese, Australian or Japanese, do share the very same features and attributes. They generate pearls that are small unlike saltwater mollusks like the Pinctada margarita pearl (commonly known pearl oyster with a black lip) and Pinctada maxima the pearl oyster with white lip. The size of these pearls range from about 2 to 11 mm. the most frequently sighted size of these pearls are between 6 to 8 mm. When all the other factors tend to be the same, then the cost of the pearls start to rise, depending on its size.

You will notice that usually akoya pearls are made into typical white strands and they tend to gradually graduate by half-millimeter increments. For example, one stand may graduate from 6 to 7 mm or from 7 to 7.5 mm. if you notice that a strand of akoya comes in a single size, say for instance single size, then it would be safer to assume that the actual size would range from 7 to 7.5 mm.

Since these pearls are bead nucleated, the time for it to culture takes about 2 years approximately. The nacre that surrounds the nucleus is usually quite thin which is quite similar to the saltwater cultured pearls. Nacre deposition is at its highest stage during summer months and tends to lessen during winters especially in Japan.
