9.0-9.5 mm Akoya Pearls

This is the largest size consistently produced by the akoya pearl oyster. While it is possible for pearls as large as 10.0 mm to grow, pearls larger than 9.5 mm are extremely rare and often exhibit poor shape and luster. For those looking for a classic strand of pearls larger than 9.0-9.5 mm, the next best option is South Sea.
