All 18ct Yellow Gold Radiant Cut Engagement Rings

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.

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.

Handmade by a family jeweller

We have been making jewellery in Bourton-on-the-Water since 1969 and are members of the National Association of Jewellers. 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.
