18ct yellow gold 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 18ct yellow gold?
18ct yellow gold is 75% pure gold, with the deep, warm colour people picture when they think of a gold ring. It is not plated, so the colour never fades. Some of our yellow gold designs hold the diamond in a white platinum head, so the stone looks as white as possible while the band stays golden. Yellow gold also flatters a slightly warmer diamond, so a stone in the H to J colour range can look just as good as a pricier, whiter one. For a lower price, see our 9ct yellow gold engagement rings.
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.
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
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.
Yellow gold reflects a little warmth into the diamond, so a near-colourless stone in the H to J range looks just as good as a whiter, more expensive one. If you want an icy white stone, choose a design with a platinum head.
