A combination of these characteristics influences the overall quality and value of pearls. Amazing Pearl uses the most commonly used and internationally recognized ranking system: A, A+, AA, AA+ and AAA to grade the pearls featured on our website.
It is important to note that freshwater pearls, unlike all other cultured pearls, are composed of solid nacre - so nacre depth is not a defined quality characteristic.
