18ct white gold marquise cut halo 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. A halo surrounds the centre diamond with a ring of smaller diamonds for extra sparkle and a bigger look.
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. The halo follows the outline of the marquise diamond, so the shape reads clearly from across a room.
Why a halo?
A halo frames the centre diamond with a ring of small diamonds. The extra sparkle makes the centre stone look larger, so it is a good way to get a big look for less. Paired with a diamond-set band, it gives the most sparkle of all.
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.
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.

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. The ring of small diamonds adds to the spread of the centre stone, so it looks noticeably larger than it would on its own.
Usually every year or two, depending on how hard the ring is worn. Re-plating with rhodium takes a short visit to a jeweller and brings back the bright white finish.
