Cushion Cut Diamond Guide by Engagement Rings Direct

Tue, 24 Apr 2012

When viewing diagram A, notice the shortening of the pavilion facets in the center of the diamond as opposed to the lengthening of them in the cushion brilliant, old mine cushion and the “X” factor (shown below). In each diagram they reach the girdle area. What this achieves is that the brilliance in the diamond reaches the exterior area or crown facets of the diamond and creates an overall brilliant diamond. The immediate question that comes to mind is why all cushion diamonds wouldn’t be cut to obtain this brilliance. The answer lies with the minimizing of weight loss. By shortening the pavilion facets the cutter has retained more weight in the diamond. To compensate for the lack of decreased brilliance the cutters have added small facets that surround the central shortened pavilion facets. As facets create the brilliance in the diamond this has given the diamond an extra amount of brilliance. However in relation to the other cushion cuts these lack the overall brilliance as the light fails to reach the crown area of the cushion. Thus you will notice that this area of the diamond lacks any cut facets and appears empty in the diagram. Technically there has been no weight loss as opposed to the other cushion cuts.
