Platinum Marquise Cut Solitaire Engagement Rings

Platinum 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 platinum?

We use 950 platinum, hallmarked in the UK. It is about 95% pure, so it is naturally white all the way through and never needs re-plating. It is heavier than gold and very hard-wearing: rather than wearing away, the metal moves over time and takes on a soft satin look, which a quick polish brings back to a high shine. It is also the best choice if you have sensitive skin.

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 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.

Handmade by a family jeweler

We have been making jewelry in Bourton-on-the-Water since 1969 and are members of the National Association of Jewelers. Your ring is made to order in 100% recycled metal, hallmarked, and ready in 3 to 4 weeks, with free UK delivery and free returns within 30 days.

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.

All precious metals mark with wear. Platinum moves rather than wearing away, so it keeps its weight and holds the diamond securely. Over time it takes on a soft satin finish, and we can polish it back to a bright shine whenever you like.
