Q. If a diamond is certified by an Independent Laboratory, such as GIA or AGS, could the quality of the diamond be judged by the certificate’s specifications and grading?

A. The value of a diamond should never be judged based on a laboratory   certificate alone. There is more to the beauty of diamonds than just specifications. The beauty of diamonds is not equal to the sum of the diamond characteristics; it is much more complex.

GIA or AGS certificate does not guarantee a fine diamond. Diamond laboratories will certify any diamond submitted for grading... from magnificent to poorly cut. Certificates simply offer an educated opinion on color, clarity, and cut of the diamond; they also record proportions of the diamond.

At Roman Jewelers, the certificate is just the first step in looking at a diamond. The second one is to always measure the beauty of the diamond with the Isee2 technology. The certificate plus measurements of brilliance, scintillation, and symmetry is what makes us so confident in the quality and beauty of the diamond.
