Platinum radiant cut solitaire engagement rings, handmade to order by our family workshop in the Cotswolds and set with a diamond you choose yourself. The radiant cut combines the clean outline of an emerald cut with the fiery sparkle of a brilliant. A solitaire holds one diamond on a clean band, so all the attention goes to the stone.

The radiant cut diamond
The radiant has the cut corners of an emerald cut but brilliant facets inside, so it sparkles more than any other square or rectangular shape. The cut corners make it hard-wearing, and it comes square or elongated. With a radiant 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 radiant diamond
Our diamond search splits radiants into square and elongated. A ratio of about 1.00 to 1.05 gives a square; 1.20 to 1.35 is a popular rectangle. The brilliant facets hide small inclusions well, so SI1 clarity often looks clean.

Frequently Asked Questions
No. Both are brilliant cuts, but a radiant has cut corners, which make it tougher and softer-looking, and it can be square or rectangular. A princess is always square with sharp corners.
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.
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.
