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 grade.
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 or shine is the
indication of how well the pearl reflects the like. A good way to think
of luster is like a mirror. It is a very import value factor for grading
pearls. 
Surface describes any divots,
small natural scratches and other pearl imperfections on the body of the
pearl.
Pearls grow in various
shapes, from baroque to perfectly round, and anywhere in between. The
roundness of the pearl can be very small, however those pearls reaching
the perfect roundness, also command the premium price. |
