What They're Saying About GIA

“Seven decades old, GIA richly deserves its recognition as the Harvard of Gemology.”

Chicago Sun Times

“If the Smithsonian can trust this organization with its crown jewels, it’s probably a good bet for you as well… [GIA is] a very good clearinghouse for information on diamonds… Combine Harvard with the Supreme Court and what do you have? The Gemological Institute of America.”

CNN Headline News

 “… Every diamond should come with a grading certificate from an accredited gemological laboratory; the jewelers we talked to agree that the Gemological Institute of America, an independent, nonprofit organization, is the most trustworthy.”

The Wall Street Journal

“I refer to GIA as the custodian par excellence of standards and integrity in our business. We at De Beers pride ourselves also on our integrity. We admire GIA as being an independent body that sets the standards of integrity that we believe to be at the foundation of continued prosperity in our business.”
