One of the most beautiful fancy shapes comes from the antique Old Mine Cut (Old German Cut). Only 120 years ago, Cushion cut was the most popular cut of the diamonds. Most of the rough diamonds until 1900 were polished as Cushions as one of the best choices among non-round diamond shapes. This shape appears as a square or rectangular pillow with rounded corners. Cushion brilliant may reveal even more dispersion (play of colors or Fire), than Round cut and almost the same level of brilliance and scintillation. It is the second by popularity after Princess, and it is one of the most beautiful ones among Fancy shape diamonds. Cushion Brilliant cut with Excellent Symmetry and Polish may display rare “Hearts & Arrows” effect. But choosing the Cushion, please pay attention to several points. First of all, take a look at Pavilion (a bottom part of the stone). It may have three kinds of facet patterns: Brilliant, French tip, and Modified cut. Brilliant cut increases the Fire, and French Tip has high brilliance. Cushion Modified cut due to the additional bottom facets helps diamond cutter get more weight from the rough diamond, but in most cases Modified cut pattern displays the “crushed ice” effect. To get the best of the Cushion cut diamond, look for the brilliant pattern pavilion or a French Tip with broad pavilion facets.
