The cushion cut diamond
The cushion cut is a square or slightly long diamond with softly rounded corners, like a pillow. Its larger facets give big, bold flashes of light, with a warm, vintage feel that goes back over two hundred years.
Why 18ct yellow gold?
18ct yellow gold is 75% pure gold, with the deep, warm color people picture when they think of a gold ring. It is not plated, so the color never fades. Some of our yellow gold designs hold the diamond in a white platinum head, so the stone looks as white as possible while the band stays golden. Yellow gold also flatters a slightly warmer diamond, so a stone in the H to J color range can look just as good as a pricier, whiter one. For a lower price, see our 9ct yellow gold engagement rings.
Choosing your cushion diamond
Our diamond search splits cushions by shape: square cushions have a ratio up to 1.08, and elongated cushions start at 1.15. Cushions can hold a little color in their corners, so G to H is a good color choice, with SI1 or better clarity.
Choose your own diamond
Every ring is set with a center diamond you choose yourself, natural or lab-grown, from our live stock. Each stone has its grading report, and the ring page shows the finished price before you buy.

Frequently Asked Questions
It is down to taste. A square cushion (ratio up to 1.08) gives a classic, soft look; an elongated cushion (1.15 and above) looks larger face up and lengthens the finger. You can search for either.
Yellow gold reflects a little warmth into the diamond, so a near-colorless stone in the H to J range looks just as good as a whiter, more expensive one. If you want an icy white stone, choose a design with a platinum head.
