A Brief History of Pearls: Size of Akoya Pearls


  A brief history of pearls

SIZE OF AKOYA PEARLS


Akoya pearls come from relatively small oysters, and as a result, the pearls themselves are typically smaller than other cultured pearls are.



Average Akoya Pearl Sizes

The average Japanese Akoya cultured pearl is about 7 millimeters in diameter. However, when they're harvested, they can range between 2 millimeters and 10 millimeters.

Graduated Pearl Strands with Akoya Cultured Pearls

Because the development of pearls depends on a natural process, it can be unpredictable. There's no way for a pearl farmer to know how large or small a pearl will be before opening the oyster, so many Akoya pearl strands feature graduated sizing.

The term graduated refers to the practice of using smaller pearls on the outsides of a strand and including larger pearls in the center. Many uniform necklaces have a range of graduation of 0.5 millimeters.
