Diamond Shapes: Cushion Cut Diamond

The Cushion Cut Diamond is a four sided deep square or rectangle cut with rounded edges and 58 brilliant facets - it has a cushioned shaped girdle. The cushion cut is an antique cut that most often resembles a cross between the Old Mine Cut (a deep cut with large facets that was common in the late 19th and the early 20th centuries) and a modern oval cut. This shape is also sometimes referred to as the pillow-cut or the candlelight diamond (a reference to cuts designed prior to electric lights, when diamonds sparkled in the light provided by candles).

The cushion, pillow or candlelight cut was developed in the 19th century and has undergone several transformations and developments since. The cushion cut has especially benefited from the invention of cleaving as this process has helped to maximise the shape’s light dispersion making it more dynamic and brilliant.

A cushion cut with a length to width ratio of less than or equal to 1.05:1 will appear square to the observer. While a squarer diamond is the preference of many, some people prefer a slightly rectangular-shaped cushion diamond with length to width ratios of 1.15:1 to 1.30:1.

Many cushion cut diamonds have a culet (small facet at the bottom of the pavilion) which can become a factor if it is visible to the eye. Where other pavilion facets reflect light back, the culet acts as a window through the diamond and thus shows the color of what ever is under the diamond. If there is white metal under the culet this window often appears as just another sparkle of light that is not be noticeable but the color of a finger might be seen, especially if the culet is big enough. A medium size culet is typically the point where a culet starts to be visible to the eye. Many medium culets are not visible to the eye but some are and most slightly large and bigger culets

The recent popularity for cushion cuts began some years ago, and the demand has increased as designers and antique dealers continue to use them. Cushion cut diamonds look especially nice in antique settings so are a great choice if that is the type of ring you are seeking.
