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 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.

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.

Under £5,000, you have access to MOH's complete range — from 2ct lab-grown showpieces to 1ct natural diamond engagement rings in premium settings. This is the price point where you can have exactly the ring you envision.

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