South Sea Pearls Grading

The A-D grading system used for Tahitian pearls, as enforced by the Ministry of Pearl Culture and the Tahitian Pearl Promotion Board (GIE) is nearly identical to that used for South Sea pearls in the current pearl market.

DawnRose Pearls only sell AA-AAA quality of South Sea pearl strand, and only choose the South Sea pearls with AA+-AAA or gem quality to assemble earring and pendant.

An overview of pearl grading factors can be found here.
