18ct yellow gold radiant cut 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. 18ct yellow gold has the rich, warm colour of traditional gold, and the colour runs right through the metal, so it never wears off.

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.
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

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.
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.
