How is poorly diamond cut?
A poorly cut 1.0-carat diamond may have the same diameter and appear as large as a 0.85-carat diamond. The depth percentage is the first indication of the quality of the cut of a round brilliant diamond. An ideal round brilliant diamond will have a depth percentage greater than 62.5 percent. Another indication of a quality cut will be the diamond’s overall diameter. A round brilliant cut 1.0-carat diamond should have a diameter of 6.5mm. The Gemological Institute of America has surpassed Tolkowsky’s mathematical model with its Facetware software, which is the culmination of 20 years of studies on diamond cuts. In 2003, the Genesis cut was developed; the cut differs in shape from the traditional cuts. The Genesis cut has concave surfaces and angles and resembles a four-pointed star. Diamonds could be cut square round, oval, and other shapes, and all diamonds are put into three main categories, which are brilliant diamond cuts, step diamond cuts, and mixed diamond cuts.
