18ct white 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 white gold gives the bright white look of platinum for a little less, and suits a diamond in any colour grade.
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 white gold?
18ct white gold is 75% pure gold, alloyed with white metals and finished with rhodium plating for a bright, mirror-white shine. It costs less than platinum and is lighter on the finger. As the plating wears, usually over a year or two, a hint of warmth can show; a quick re-plate brings it back. Want to spend less again? See our 9ct white 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 colour in their corners, so G to H is a good colour choice, with SI1 or better clarity.
Choose your own diamond
Every ring is set with a centre 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.
