As a board member of the American Gem Society, Louis understands the importance of cut quality as it pertains to the value of a diamond. We have invested in a tool designed by the AGS Laboratories that allows us to prove exactly how precise the cut quality of the diamond in question is, and to give you the client, a visual representation of its symmetry and proportion. Come by for a demonstration or an evaluation of your own diamond.
The AGS Angular Spectrum Evaluation Tool (ASET)
WHAT THE COLORS MEAN:
Red represents light coming from angles where there is likely to be bright, direct sources of illumination in most viewing environments. This color is dominant in the ASET image of a well-cut diamond.
Blue corresponds to light that normally is blocked by the viewer’s head and body. An ASET image with a moderate amount of this color in an attractive pattern means the diamond has good contrast.
Green is produced by low-angle light, which usually is reflected from walls or other objects in the surrounding area (rather than coming from direct sources). A diamond with a high cut quality may show small amounts of this color around the bezel area of the ASET image.
Black or White appears in areas that do not return light under real-life viewing conditions. If a diamond is well cut, the ASET image will show only very small areas of black or white around the outer edge (and perhaps none).
