Modern Mikimoto earrings start around a value of $300, while necklaces can cost upwards of $3,000. Vintage Mikimoto items in good quality have even higher values. The value of Mikimoto pearls depends on the age and condition of the pearls, as well as the type of jewelry.
The value of a piece of pearl jewelry is also affected by the size and grade of the pearls as well as the other materials used in the item. For example as of September 2014, a pair of Mikimoto pearl earrings made of AA grade, 6-6.5 millimeter pearls retails for just over $480, while a pair of earrings made of AAA grade, 8 millimeter Mikimoto pearls is valued at over $2,500.
Mikimoto pearls rose to popularity in the early 20th century and are considered some of the highest-end pearls, which is why vintage Mikimoto pearls are so valuable.
