The Gemological Institute of America is the largest and perhaps most respected of the nonprofit Institutes that specialize in diamond grading, research, and education. It was founded in 1931; it has over 1,100 employees consisting of scientists, diamond graders, and educators. They are the publishers of an award winning quarterly journal, Gems & Gemology.
GIA is the creator of the world famous 4C grading standard of diamond value. The 4Cs are color, clarity, cut, and carat weight. They also developed the trademarked International Diamond Grading System. There grading standards are recognized worldwide by almost every professional jeweler as well as educated diamond buyers. The GIA Diamond Grading Report and the GIA Diamond Dossier are recognized as the preeminent diamond credentials.
Because of their reputation for strict grading and their excellent reputation, the GIA is usually the Institute of choice for high quality diamonds, and samples of all sizes and shapes arrive from every corner of the globe for analysis and grading.
Some of the famous diamonds that have been graded by GIA include the Hope Diamond (45.52 carats), the De Beers Millennium Star (203.04 carats), and the Incomparable Diamond (407.48)
Education is another important function of the GIA, and the highly prestigious Graduate Gemologist (G.G.) diploma is recognized widely as the mark of a senior professional jeweler. Even the White House and the United States Congress have sought answers on diamond related matters from the GIA. There own advertising claims that the GIA is where the bibles of gemology are being written every day.

Have been doing my research on the Gemological Institute of America (GIA), crazy/very cool that they’ve graded the Hope Diamond, the De Beers Millennium Star and the Incomparable Diamond - however, I’m not surprised.
As mentioned above they are definitely the highest regarded institution and the ultimate authority on gemology in the jewelry industry, as acknowledged by the U.S. government - impressive. I was initially very skeptical about the entire process of buying a diamond, but the GIA Diamond Grading Report allowed me to efficiently compare the diamonds I was interested in with confidence, especially knowing they are independent and a nonprofit.
It is wonderful that an organization exists with the sole interest of the consumer, as buying a diamond can be very overwhelming. Their site is a great resource http://gia4cs.gia.edu for anyone looking to learn. I will continue to rely on GIA grading for any future purchases as I did with buying an engagement ring for my girlfriend. Literally, everyone I speak with insists on a GIA report prior to buying a diamond whatever the price range.
Thanks for the post!
