If we talk about Tahitian pearl grading, then there is no definite number system or recognized letter system for it. All Tahitian pearl dealers used to follow some best pearl-grading practices that are accepted worldwide. These practices are considered as the best practices and are recognized by all professionals within the pearl industry. In order to get the best Tahitian pearl it is important to understand the grading features and quality characteristics of Tahitian pearls. Tahitian pearl grading will definitely help you in comparing various pearls and get you the one you are looking for.
There are six factors in pearl grading: shape, luster, size, surface quality, nacre thickness, and colour that makes the overall pearl-grading system. Each of the gems has different value factors of all these quality attributes, and that makes each one of them most unique and precious. It is possible to measure and grade each grading factor individually, but most of the Tahitian pearl traders find the letter system grade more reliable.
There are basically two pearl-grading systems that are followed internationally which are AAA-A and A-D. A-D is also known as the Tahitian grading system, and the AAA-A system was popularized by the late Kokichi Mikimoto. In the U.S. both systems are used widely for pearl grading. In producing countries like French Polynesia and Australia, the A-D system is used by all Tahitian pearl producers. However, if we talk about Hong Kong, then these people utilize the AAA-A system while selling Tahitian pearls to wholesalers. As there is no internationally recognized pearl-grading system nor is there any number system or alphabetical system, both systems of grading are widely acceptable. The alphabetical grading system used to analyze these Tahitian pearls basically depends on the place you are getting these pearls from. So you can believe in either system as both the systems are absolutely correct and completely acceptable everywhere.
