What is GIA?
Founded in 1931, the Gemological Institute of America (GIA) is the world’s foremost authority on diamond quality. GIA developed the industry standards for grading diamonds, including the essential 4 Cs: cut, clarity, color, and carats. GIA is not a jeweler, however: it is a non-profit research and educational institution dedicated to preserving honesty and integrity in the diamond industry as well as fostering public trust in fine gems and jewelry. More than 1,100 employees in research centers, grading labs, and classrooms throughout the world – including New York, Hong Kong, Tokyo, Moscow, and many more locations – seek to represent the best of the diamond industry through meticulous work and dedication. The GIA has been questioned by the White House and Congress on matters relating to gemology, and a degree from GIA is a prestigious credential. GIA has graded many famous gems, including crown jewels, celebrities’ stones, and the revered Hope Diamond.
