Radiant Cut Side Stone Engagement Rings in 18K Yellow Gold Under £2,000

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.

Warm, timeless, and universally flattering. 18K yellow gold contains 75% pure gold and has a rich, warm tone that has been the traditional choice for fine jewellery and engagement rings for centuries. Its natural colour will never fade or require re-plating.

Under £2,000, you can find a 1ct lab-grown diamond engagement ring in your choice of metal and setting style. This price point represents the most popular budget for lab-grown diamond engagement rings — genuine luxury without compromise.
