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

a mirror. It is a very important
value factor for the overall grade
of the pearls.
