What is a Certificate?
When retailers offer their own certificate of authenticity, you are not getting a verified review from an independent, internationally-recognized organization such as the International Gemological Institute (IGI), European Gemological Laboratory (EGL) or Gemological Institute of America (GIA). These are the world’s largest and most respected laboratories for the independent grading and evaluation of diamonds and fine jewelry.

Gemological Institute of America (GIA)
Founded in 1931, Gemological Institute of America (GIA) is actively engaged in research to advance the science of gemology. In 1953, the GIA developed its International Diamond Grading System and the 4Cs (cut, clarity, color, and carat weight) as a standard to compare and evaluate the quality of diamonds. The GIA was also responsible for the first modern diamond grading reports, where it introduced various grading methodologies for diamond. These scales and methods have been the standard within the gem trade for characterization of diamonds ever since. Today, the institute is headquartered in Carlsbad, California and operates out of 14 countries, with 12 campuses, 7 laboratories and 4 research centers worldwide
