The grading of freshwater pearls is more variable than that of saltwater pearls because freshwater pearls are more colorful and of various shapes. But we can still generally assess their value according to the 7 factors:
Luster and Nacre

After the first harvest, mussels can spontaneously grow pearls a second time. That means cultured freshwater pearls either do not have nucleus or have a very little one inside, hence, freshwater pearls are make up with very thick nacre.
Only those freshwater pearls with EVENLY high luster can be considered as high valued ones. Judge luster see Luster and Nacre.
Blemishes such as discolorations, pits, bump, wrinkle and cavities can decrease the value of pearls.

Iridescence increases the value too.
Natural color pearls are more valued than treated ones.
By inserting different shapes of nuclei, people can harvest some unique shapes freshwater pearls as they desiring. Thin shapes freshwater pearls tend to sell for less than fatter-looking ones. Symmetry and round are of higher value than baroque.
Size for freshwater is not as important of a price factor as is luster and surface quality. But it still sticks with the rule of the larger, the more valuable.
