The most common cut is modified cushion, which accounts for a whopping 98 percent of the cushion cuts made. The stone exhibits crushed ice look with no discernable pattern to its facet. Observers are often left feeling as if they are looking at pieces of broken glass or crushed ice- hence the name. The facets at the center appear to blend into each other. The numerous facets leak large amounts of light and reflect light in a chaotic needle-like pattern that dulls the stone's sparkle and brilliance.

Its counterpart, the cushion brilliant, is modeled after the round brilliant. It has several pavilion facets such that when viewed from the top, a crisp, clear pattern can easily be identified. The facets extend from the center of the stone to the girdle forming a star-like pattern. Such diamonds are hard to find in the market, and the ones available usually cost a pretty penny. Nevertheless, the cushion’s brilliant, precise cut, larger-than-average face-up size, and superb brilliance make the stone well worth its exorbitant price.
When it comes to evaluating the cut of a cushion diamond, it is vital that one does not solely rely on the GIA reports. Nothing on the certificate will tell you whether the cushion cut diamond has a crushed ice or star-like look. The report will also not indicate the edges' roundness or square shape, a quality subject to personal preference. Purchasing cushion cut diamonds with excellent cut without a physical inspection of the stone or its accompanying clear, magnified photos has been likened to separating crushed ice from broken glass- a difficult task in even the best circumstances.
