Freshwater Pearl Grading System

Freshwater Pearl Grading System

While there is not, as yet, any industry-wide grading system for pearls, the two most commonly used systems recognized by most reputable dealers are the A-AAA system and the A-D system (more commonly used for Tahitian pearls).

We only sell the AA+ and AAA quality of Freshwater Pearls*, and a lot of them feature with ultimate gem quality with extreme high luster and unblemished surface.

An overview of pearl grading factors can be found here

*The AA/AAA 6.0-7.0mm white double and triple strand is the ONLY product we sell which contains some AA freshwater pearls. This is only to make the starting price of multiple pearl strands to be more affordable to meet some customers’ requirement. All of the rest of our Freshwater pearls are absolutely AAA/AAAA quality. 

**Pearl diameter is measured by the caliper with a precision of less than 0.04mm. The diameter difference is calculated as (Maximum diameter-minimum diameter)/average diameter.

Matching Grading (for multi-pearl jewelry only)
