Cushion Cut Diamonds Also know as pillow-cut diamonds, cushion cut diamonds are similar in shape to the radiant cut, but with softly rounded corners. Popular for more than a century, this diamond’s large facets maximise its brilliance and highlight the stone’s clarity.
Cushion cut diamonds are extremely pretty and comparatively rare so this shape is likely to stand out as being a little different if you choose it for your diamond engagement ring. Cushion diamonds cut to a ratio of 1:1 are squarer in shape, while those with a ratio greater than 1:1.15 are more rectangular. |
