Diamond Buying Made Easier > Diamond Grading > GIA DiamondsGIA DiamondsGIA diamonds???... I didn't know that GIA sold diamonds! Well actually, GIA doesn't sell diamonds! GIA sells services. GIA provides all types of services to the jewelry industry and to consumers alike. One of the most well known GIA services comes from one of its divisions, the Gem Trade Laboratory (GTL). The Gem Trade Laboratory's principal services and reports- * Diamond Grading Report * Diamond Dossier (for diamonds weighing less than 1.00 ct.) * Colored Diamond Grading Report * Colored Diamond Identification and Origin * Gemological Identification * Pearl Identification * Laser Inscription When you see the commonly used term "GIA diamonds" it means that someone is selling a diamond along with some sort of report from GIA's GTL. I don't see as many advertisements that offer AGS diamonds, EGL diamonds, IGI diamonds, etc. This commonly seems to be associated with GIA.... which only reflects the stature that GIA has when it comes to diamond grading reports. A "GIA Cert"
GIA "certifies" nothing! To certify something means that it has been established as an absolute fact.... such as a birth certificate, a death certificate, etc. A person's birth or death isn't an opinion, it is a fact. The 4C's associated with a diamond grading report is the collective opinion of the graders at GIA that graded the diamond and nothing more. It might sound like I'm "knit picking" a bit when I say that "GIA certified diamonds" is not technically correct... but I thought it was important to point it out. GIA does state the following on their website- "The Gemological Institute of America does not certify anyone or anything. Neither a student nor a graduate who has been awarded a certificate or diploma, nor a gem which has been graded or identified by GIA has been "certified" by GIA." GIA's GTL is good, actually very good, at what it does and to have a diamond with a grading report issued from them is reassuring. A diamond grading report from GIA will carry a premium verses a diamond grading report from most other labs. If I get a diamond grading report from GIA (New York), I am 99.999% certain that if I were to turn around and send it to GIA (Los Angeles) it would come back with the same grades. This would not be the case if I were to do the same thing with EGL, European Gemological Laboratory. - Important Take Away Points - |
