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.

Made to order in the Cotswolds

Every ring is made to order in our family workshop in Bourton-on-the-Water, where we have made fine jewellery since 1969. We use 100% recycled precious metal, every ring is independently hallmarked, and each one takes 3 to 4 weeks. Delivery is free across the UK, and returns are free within 30 days.

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.

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.
