Cushion cut diamonds (also known as pillow cut) have round corners and wide surface to bring out their radiance and glow. They have been in demand for more than a century.
Cushion-cut diamonds are available in square and rectangular shapes. The length to width ratio of a cushion diamond will determine how it looks from the top. To find the dimension of cushion you want, look for the length-to-width ratio in our interactive diamond search and on each diamond’s detail page. For a cushion-cut diamond that is square, look for length-to-width ratios between 1 and 1.05. If you prefer more of a rectangular shape, look for length-to-width ratios greater than 1.15.
