Mikimoto introduces South Sea grading system

New York—Pearl house Mikimoto has created a grading system for its South Sea cultured-pearl collections.

The proprietary system, similar to Mikimoto's Akoya grading system established in 1974, gives each pearl a grade based mainly on the luster and surface perfection of the gem. The system does not reflect a pearl's shape, size and color, but those factors do contribute to the pearl’s value.

Pearls receive grades from A to AAA. A AAA South Sea pearl represents the most perfect possible pearl.
