Marquise Lab-Grown Diamond Halo Engagement Rings in 18K White Gold Under £10,000

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 marquise cut features a distinctive elongated shape with pointed ends, offering the largest face-up area of any diamond shape for its carat weight. Its boat-like silhouette creates a dramatic, regal presence on the finger and makes the stone appear significantly larger than other shapes of the same weight.
