Tahitian Pearl Grading

The A - D System (or Tahitian System)

This system grades pearls on a scale from A to D, with A being the highest grade. This is the system used in French Polynesia (based on a government standard there) to grade Tahitian pearls. It is therefore sometimes referred to as the "Tahitian system." To make your shopping experience easier at PearlsOfJoy.com we utilize the AAA-A system for all of our pearls. Below is an explanation of the tahitian system and how it relates to the grading used at PearlsOfJoy.com

Tahitian System
Grade
Pearls Of Joy
Grade
Description
A AAA The highest-quality pearl, with very high luster with only minor imperfections over less than 10% of its surface. These imperfections are then used as marks for drill holes.
B AA+ High or medium luster. Surface may have some visible imperfections, but over no more than 30% of its area.
C AA Medium luster with surface defects over not more than 60% of the surface area.
D A May have many slight defects, but no deep ones, spread over 60% of its surface; or deep defects over no more than 60% of its surface; or a combination of minor and deep defects over no more than 60% of its surface. In this grade of pearl, the luster is irrelevant. Even the most lustrous pearls will be graded D if their surface is blemished to this extent.
