Cushion Cut Diamond Engagement Rings: A Guide
Soft, romantic and full of sparkle — what defines a cushion cut diamond and how to choose one for an engagement ring.
Quick answer
A cushion cut is a square-to-rectangular diamond with gently rounded corners, like a pillow. It combines a vintage feel with plenty of brilliance, hides colour well, and suits solitaire, halo and three-stone settings. Made to order in solid 9, 14 or 18ct gold, with natural diamonds graded by GIA or HRD and lab-grown by IGI.
What is a cushion cut?
A cushion cut is a square or slightly rectangular diamond with softly rounded corners — the shape of a pillow, which is where the name comes from. It is one of the oldest cutting styles, giving it a warm, vintage character, but modern faceting gives it lively brilliance too. It's a favourite for anyone who wants sparkle with a soft, romantic outline.
What to look for
Cushion cuts come in more square or more rectangular outlines — choose the length-to-width ratio you prefer (around 1.00 for square, higher for elongated). Their faceting is forgiving with colour, so a slightly lower colour grade can still look bright. Cut quality drives the sparkle most. Our diamond 4Cs guide explains how the four factors balance.
Settings that suit it
The cushion is versatile. A solitaire on a plain or pavé band lets the soft shape shine; a halo emphasises size and adds sparkle around the stone; a three-stone setting frames it with side diamonds. Rounded corners also make it comfortable and secure for everyday wear. To see halo settings in solid gold, browse our halo and double halo rings.
