18ct rose gold cushion cut engagement rings, handmade to order by our family workshop in the Cotswolds and set with a diamond you choose yourself. The cushion cut has softly rounded corners and large facets, with a romantic, vintage glow. 18ct rose gold has a soft, romantic pink color that flatters every skin tone and gives a classic design a modern feel.
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 rose gold?
18ct rose gold is 75% pure gold, warmed to a soft pink by a little copper in the alloy. It is not plated, so the color never wears off, and it is slightly harder than yellow gold. Some of our rose gold designs set the diamond in a white platinum head for the whitest look, with the pink band around it. For a lower price, see our 9ct rose 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.

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.
No. The color comes from the copper in the alloy, all the way through the metal, so there is no plating to wear off. If anything, rose gold warms slightly with age.
Yes. Every ring can be set with a natural or lab-grown diamond from our live stock. Both are real diamonds; lab-grown stones cost less for the same size and grade.
