Radiant Cut Lab-Grown Diamond Halo Engagement Rings in 18K Yellow Gold Under £3,500

Yellow gold with a lab-grown diamond creates a warm, vintage-inspired look at an accessible price point. The traditional warmth of yellow gold paired with the modern value of lab-grown creates a ring that honours heritage while embracing innovation.

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.
