About Gia Diamonds
GIA stands for Gemological Institute of America, as is widely considered as the standard-bearer of the diamond certification industry. Everything that the GIA does is focused on education, whether it’s for the consumer or the jeweler.
An important factor that makes the GIA our top choice for diamond certificates is the fact that they are truly an independent, non-profit entity. Every diamond that is inspected by the GIA is viewed by four expert gemologists, and it’s impossible for jewelers to “game” the system by getting grades that are better than what the diamond actually is.
About Gia Diamonds Report
A GIA diamond grading report gives you all the important information you need to know about a diamond’s 4Cs, as well as its fluorescence, any treatments and more. With a GIA diamond grading report, you can be sure that your diamond is a natural diamond. That’s because GIA has examined and tested the diamond using the most sophisticated instruments and procedures available, informed by the Institute’s ongoing scientific research.
Since a GIA diamond grading report is an unbiased assessment of a stone’s quality characteristics, it lets you compare one GIA-graded diamond to another. This empowers you to compare the quality of loose diamonds and decide which one is the best value and right for you.
Check your diamonds
Making sure the diamond you’re eyeing comes with a GIA diamond grading report is like getting an independent inspection before you buy a car or house. It’s a smart step in your purchase process – and many insurance companies will require a GIA grading report as a basis for insuring your diamond.
To be sure your diamond was graded by GIA, ask to see its GIA grading report. In addition to a full assessment of the diamond’s 4Cs, the GIA report contains a unique number, which is also sometimes inscribed on the diamond’s girdle. You can use the report number to access GIA’s online global report database, GIA Report Check, to verify that the diamond is GIA graded and view all its grading details.
An original GIA diamond grading report will have the Gemological Institute of America logo in the upper left. GIA GEM TRADE LABORATORY will be at the top of the document, with addresses and phone numbers, and the document will be laminated. The report will have a number. The position of this number will vary depending on the date issued.
Recent documents have the number in the upper left hand corner under the GIA logo. Below that number will be the date of the document. Other places in which the report number will appear will often be to the right of the centered “DIAMOND GRADING REPORT” just below the addresses and the phone numbers of the lab.
GIA Diamond Grading Scales: The Universal Measure of Quality
Published March 14, 2013
The prospect of purchasing a diamond may seem daunting, but through GIA, an unbiased authority on diamonds, you have several handy resources to help you select the highest quality diamond. First up, an overview of the 4Cs: Color, Clarity, Cut, and Carat Weight.
GIA created the 4Cs (Color, Clarity, Cut and Carat Weight) as a universal method for establishing the quality of any diamond, anywhere in the world. The 4Cs means two very important things: diamond quality can be communicated in a universal language, and diamond-buying consumers can know exactly what they are about to purchase.
