Radiant Cut Lab-Grown Diamond Three Stone Engagement Rings in 18K Rose Gold Under £3,000

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.
