A round brilliant surrounded by a halo of melee diamonds creates maximum sparkle from every angle. The halo frame adds approximately 0.5ct of visual size, making a 1ct centre stone look closer to 1.5ct.

The round brilliant cut features 58 precisely arranged facets mathematically optimised to maximise light return, fire, and scintillation. Accounting for over 60% of all engagement rings sold worldwide, the round brilliant is the most researched and refined diamond shape in existence. Its symmetrical silhouette offers unmatched sparkle from every angle.

A halo setting surrounds the centre diamond with a border of smaller pavé diamonds, creating a frame of light that makes the centre stone appear 20–30% larger. Halo settings add vintage character and maximum sparkle, catching light from every angle.

The £1,000–£1,500 range opens up a wonderful selection of lab-grown diamond engagement rings with larger centre stones and more setting options. This is one of the most popular budget ranges for couples choosing lab-grown diamonds.

Round halo rings deliver the most brilliance per pound — the halo amplifies the round's already exceptional fire.
