Pearls have several magnificent characteristics and based on these, the grading of the pearls is done. There is a very popular grading system for the pearls called the Tahitian system which is also acknowledged worldwide because of its universal applicability on black Tahiti pearls and south sea pearls which are saltwater. The Tahitian way is mainly designed for the grading of the saltwater ones on the scales A, B, C and D. In here, the pearls of the best quality come under the A category with D being the lowest category. The pearls whose quality are lower than D aren???t used for making any sort of jewelry or for exportation. These are just used for making pearl powder which is only sold in the region of Tahiti.
