WHY DON'T THE MAJOR GEM LABS GRADE CUT QUALITY FOR RADIANTS?

Evaluating the beauty of a Radiant Cut is so complicated that none of the major gem labs grade cut quality for Radiants.

Recently, the Gemological Institute of America began issuing a "cut grade" for round diamonds. They do not, however, issue a "cut grade" for radiant cuts. Why not?

With a round diamond, it is possible to reliably predict the appearance of a diamond simply by measuring various proportions. The GIA issues a cut grade based on whether those proportions fall into the ranges that the lab considers optimal.

Radiant cuts, however, involve far more variables than round diamonds. The "hybrid" nature of the cut, which combines elements of the kite shaped faceting of a round brilliant and the rectangular step cut faceting of a traditional emerald cut, creates a far more complicated pattern of light reflection. Each Original Radiant Cut reflects light in numerous ways within the diamond. In addition, radiants vary in shape from square to rectangular, and each diamond must be proportioned properly for its unique characteristics.

It is important to understand that due to the different radiant shapes, and complexity of the cut, the radiant cut cannot be reliably evaluated by proportions alone. Radiant cut quality can ultimately be determined only through a combination of proportion standards and a visual examination by experts experienced in evaluating radiants. As the developers of this revolutionary cut, our expertise in evaluating cut quality for radiants is second to none. We ensure that only a diamond true to Henry Grossbard's vision of a square or rectangular shape bursting with life can be sold as an Original Radiant Cut.
