The most expensive cut of diamond is the round brilliant. Gemologists estimate that a round cut diamond may cost as much as 30% more than a similar fancy shaped diamond for several reasons. For one thing, it takes much more raw material to cut round brilliant diamonds and to ensure the demanding proportions that maximize the potential brightness of the stone are met. It is also due to the much larger demand for round cut diamonds.
It is a common misconception that a diamond’s cut is the shape of the stone such as round or oval. Rather the cut of the diamond describes how well the stone’s facets interact with the light. The Gemological Institute of America (GIA) says the proportions of a precision-cut standard round brilliant diamond affect the brightness of the diamond (the amount of internal and external white light reflected). It also affects the fire, which is the scattering of the white light into all the colors of the rainbow, and finally the scintillation or the amount of sparkle the diamond produces.
They add that, “precise artistry and workmanship are required to fashion a stone so its proportions, symmetry and polish deliver the magnificent return of light only possible in a diamond.” The “ideal cut” allows the maximum amount of light to return through the top of the diamond and takes into account the depth, table size, crown height and angle, girdle thickness and more. Gemologists carefully evaluate a rough stone to determine the best cut that will offer the maximum clarity, color and carat weight.
While all of this may sound complicated, it does help to have a rudimentary understanding of how the cut affects the stone’s sparkle and brilliance as well as to only shop with a highly-respected jeweler. Diamonds are an investment and it pays to make an educated decision.
