18ct white 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 white gold gives the bright white look of platinum for a little less, and suits a diamond in any colour grade.
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 white gold?
18ct white gold is 75% pure gold, alloyed with white metals and finished with rhodium plating for a bright, mirror-white shine. It costs less than platinum and is lighter on the finger. As the plating wears, usually over a year or two, a hint of warmth can show; a quick re-plate brings it back. Want to spend less again? See our 9ct white 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.
