18ct white gold marquise cut engagement rings, handmade to order by our family workshop in the Cotswolds and set with a diamond you choose yourself. The marquise is a long, boat-shaped diamond with two points. It looks larger than any other shape of the same weight. 18ct white gold gives the bright white look of platinum for a little less, and suits a diamond in any colour grade.
The marquise cut diamond
The marquise is a long brilliant cut with a point at each end. It has the largest face-up area of any diamond shape for its weight, so it looks big for its carat weight and makes the finger look long and slender. It has a bold, vintage character.
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 marquise diamond
A ratio of 1.75 to 2.25 gives the classic shape; keep the two halves even. Like the oval, a marquise can show a bow tie, so check the photos. The two points are the delicate part, and our settings protect each one with a claw.

Frequently Asked Questions
The points are the thinnest part of the stone, so they can chip if knocked. Our marquise settings hold each point in a claw to protect it.

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.
