White South Sea Grading Guide - Pearls Only

Overall Grade

Using the AAAA Pearl Quality Grading
System the Overall Grade offers HIGHEST
value to our customers since some value
factors can be higher than the overall

Just like in the example on the
right, the pearl necklace has AAAA
Luster and AAAA Shape however it
is still assigned just a grade of AA
because the Surface is AA

Luster Grade

Luster or shine is the indication of
how well the pearl reflects the light.
A good way to think of luster is like
a mirror. It is a very important
value factor for the overall grade
of the pearls.
