Radiant Cut Solitaire Engagement Rings in 18K White Gold Under £5,000

White gold solitaire delivers the same bright, modern look as platinum in a lighter, more affordable package. The neutral white metal lets the diamond take centre stage while the 18k gold ensures lasting quality.

The radiant cut combines the elegant shape of an emerald with the brilliant-cut faceting of a round, producing exceptional fire in a rectangular or square silhouette. Its cropped corners give it a distinctive look that is both modern and versatile, while its faceting pattern hides inclusions well.
