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.

An engagement ring does not need to cost a fortune to be meaningful. Under £1,000, lab-grown diamond rings offer genuine sparkle and certified quality at an accessible price. At MOH, every ring in this range is handcrafted in Hatton Garden with the same care as our most expensive pieces.

Round solitaires are the most purchased engagement ring style worldwide.
