The natural diamond solitaire is the most iconic engagement ring combination in existence. Nothing compares to the simplicity of a single natural diamond, formed over billions of years, set in a minimal mount that lets nature's masterpiece speak for itself.

The heart shape is the most overtly romantic diamond cut — a modified brilliant with a distinctive cleft at the top. It requires exceptional cutting skill to achieve symmetrical proportions and balanced lobes. Heart shaped diamonds are a bold, meaningful choice for those who want their engagement ring to make a romantic statement.

Warm, timeless, and universally flattering. 18K yellow gold contains 75% pure gold and has a rich, warm tone that has been the traditional choice for fine jewellery and engagement rings for centuries. Its natural colour will never fade or require re-plating.

The £2,000–£3,000 range unlocks larger lab-grown diamonds (1.5ct+) or your first natural diamond engagement ring. This is where the full breadth of MOH's collection becomes available.

A natural solitaire focuses your investment on the stone — the most enduring part of the ring.
