Radiant Cut Lab-Grown Diamond Halo Engagement Rings Under £3,000

A halo setting amplifies a lab-grown diamond's already impressive value proposition. The halo frame makes the centre stone appear 20–30% larger, and combined with lab-grown pricing, you can achieve a truly spectacular ring.

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.
