Platinum and natural diamond is the most traditional luxury engagement ring pairing. Both are rare, enduring, and increase in beauty over time. This combination is the choice of heritage jewellery houses and has graced the most celebrated engagement rings in history.

The radiant cut combines the elegant shape of an emerald with the brilliant-cut faceting of a round, producing exceptional fire in a rectangular or square silhouette. Its cropped corners give it a distinctive look that is both modern and versatile, while its faceting pattern hides inclusions well.

The purest choice for a lifetime of wear. Platinum is 95% pure, naturally white, and will never fade or yellow over time. It is denser and heavier than gold, giving your ring a satisfying weight and substance. Platinum is hypoallergenic, making it ideal for sensitive skin.

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.

Natural diamond in platinum represents the highest investment but also the most enduring choice.
