Why everyone prefers GIA Diamonds

If you are educating yourself on how to buy diamonds, then you have surely come across diamond certificates and diamond grading. When you buy certified loose diamonds, it means that an objective gem laboratory such as GIA, IGI, AGS or HRD as assessed the quality features of the diamond according to their own methods and grading system. This includes the 4Cs (carat, clarity, color and cut) as well as many other features. When it comes to diamond grading, the most accurate gem laboratory is without a doubt the GIA. The GIA is considered to be the most authoritative source on diamond grading, as they uphold the highest standards recognized by the diamond industry worldwide. In fact, the grading systems from other gem labs are adapted from the original loose diamond grading system developed by the GIA. That is why true diamond experts will always prefer to work with GIA certified diamonds.

Understanding GIA Certification

gia certified diamondsThe GIA certificates issued with graded loose diamonds are actually fairly easy to read, once you know what you are looking at. The GIA report number is an identification code that matches a grading report to a diamond. The grading report number is laser inscribed on the girdle of the diamond, visible under 10x magnification. The measurements are important to a diamond’s shape and sparkle, and every diamond shape has different ideal measurements. The 4Cs are noted in the grading results, which in the GIA certificate shown here are 3.01 carat F color VS1 clarity and Excellent cut grade. Polish and Symmetry are part of the cut grade, and if all three are graded excellent by the GIA, then we call it “triple x”. This particular 3 carat diamond has a medium fluorescence, which will decrease its value when compared to an identical diamond with no fluorescence.
