What pearl classification system does GIA use?
GIA uses a comprehensive standard it developed over a 70-year period of ground-breaking research on pearls, called The GIA 7 Pearl Value Factors™ (Size, Shape, Color, Luster, Surface, Nacre, and Matching).
The GIA 7 Pearl Value Factors™ provide a systematic way to evaluate pearls of all types, and to describe their appearance and quality in a way everyone can understand.
