Pearl Quality Guide
Premium Pearl grades pearls from A, AA, to AAA Quality. AAA Quality pearls have the highest quality, exceptionally high luster, and flawless surface.
There are several factors that determine the quality and value of the pearl: luster, nacre thickness, surface texture, color, shape, size and matching. A combination of these characteristics decides the overall quality and value. Luster is the mirror-like quality of a pearl. It is the amount of light that reflects off a pearl's surface.
