The Radiant Diamond
The Radiant cut diamond was the first square cut diamond to have a complete brilliant cut faceting pattern, which is why the Gemological Institute of America will classify the Radiant cut as a modified square or rectangular brilliant cut. For those that love the shape of the traditional Emerald cut diamond, but prefer the brilliance of a Round brilliant cut diamond, the Radiant is the perfect marriage between the other two cuts.
Currently, no laboratory will tell you what an ideal cut is for the Radiant Cut diamond, but there are a few parameters that you may follow to steer you in the right direction towards what will appeal the most to your eye. The first thing that we look at is the length to width ratio, how long is the diamond, compared to how wide the diamond is. There are different ways to view a well cut Radiant diamond depending upon if your eye prefers the look of the square shape or the rectangular shape, both of which are available in the Radiant Cut;
The chart that we have devised below may help to give you a general guideline for evaluating the cut of an Radiant cut diamond, although nothing works better than visually inspecting a diamond yourself to see what dimensions are most attractive to your eye, after all, it is your visual appeal that you will want to enjoy for many years after purchasing your Radiant Cut diamond.
