The natural round brilliant is the quintessential engagement ring diamond — the combination of geological rarity, unmatched brilliance, and timeless appeal. Formed over billions of years and cut to mathematical perfection, it is the choice for those who want nothing less than the original.

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.

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.

Natural round diamonds command the highest per-carat price due to material loss during cutting and overwhelming demand.
