The Gemological Institute of America has been entrusted with grading some of the world’s most famous diamonds and brings the same unmatched expertise to grading yours. Independent and nonprofit, GIA is considered the final word on a diamond’s authenticity and quality. GIA developed the 4Cs and the International Diamond Grading System™, the standard used around the globe.
GIA screens every gemstone to identify synthetics, simulants and known treatments. Expert gemologists examine each diamond under controlled lighting and viewing conditions, in order to provide the most rigorous assessments of a diamond’s 4Cs. Every GIA grading report contains these assessments along with additional descriptive information and state-of the-art security features. Buying a diamond is a momentous decision. GIA reports let you make it with confidence. |
