18ct rose 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 rose gold has a soft, romantic pink colour that flatters every skin tone and gives a classic design a modern feel.
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 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 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.
