18ct rose gold marquise cut solitaire 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 solitaire holds one diamond on a clean band, so all the attention goes to the stone.
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. With a marquise diamond, a solitaire shows off the full outline of the stone.
Why a solitaire?
A solitaire is the purest engagement ring: one diamond on a plain band, with nothing to compete with the stone. It never dates, lets more light into the diamond than any other setting, and sits easily beside almost any wedding ring.
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 colour 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 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. A plain wedding band sits neatly beside most solitaires, and if the setting sits low, a shaped band fits around it. Our wedding ring designer makes matching plain bands.
No. The colour 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.
