The round solitaire is the most iconic engagement ring of all — the design that started it all. A single round brilliant held aloft by a minimal setting is timelessly elegant, universally beautiful, and will never go out of style.

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 solitaire is the purest expression of an engagement ring — a single diamond held aloft by a minimal setting, letting the stone speak entirely for itself. Solitaire settings have been the most popular engagement ring style for over a century, prized for their timeless simplicity and the way they showcase the diamond without distraction.

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 solitaires are the most purchased engagement ring style worldwide.
