Tahitian Pearl Grading

Tahitian Quality Grading Guide

PearlsOnly uses the AAAA Pearl Quality
Grading System to grade its Tahitian
pearls.

All Tahitian pearls are graded and
assigned a grade on these following value factors:

  • Luster
  • Surface
  • Shape(Roundness)

All of the Tahitian Pearls at PearlsOnly
are graded on the 3 value factors.

Tahitian Quality Grading Guide

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
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 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.

Body (Surface) Grade

natural scratches and other pearl
imperfections on the body of
the pearl.

Shape Grade

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 most expensive price.
