Can You Help Me Understand "AAAA" Pearl Grading Scales?



Pearl Grading Questions

 

 

We Answer: 

Absolutely! Pearl grading is easy once you understand the A-AAA and A-AAAA Grading Scales used for the various pearl types. 
 
The A-AAA Pearl Grades are also known as the Japanese Grading System, and applies specifically to Japanese Akoya pearls. In this grading system, "A" represents the lowest, most commercial grades, and "AAA" represents the highest grades with the most beautiful pearls.  
 
The A-AAAA Grading System is applied to all other pearl types: Freshwater pearls from China, black Tahitian pearls from French Polynesia, and White and Golden South Sea pearls. It is similar in structure to the AAA Japanese System, with "A" representing the commercial grades, and "AAAA" represents the very highest qualities.

Both the A-AAA (Japanese Akoya) and A-AAAA (Tahitian, South Sea and Freshwater) Grading System uses all 7 Value Factors to evaluate our pearls and assign each strand or pair of earrings its spot on this easy to understand scale.
 
In this post, let's examine the A-AAAA Quality pearl grading scales so you can get more familiar with what each pearl grade should look like.
