Radiant Cut Natural Diamond Halo Engagement Rings in Platinum Under £2,000

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.

Under £2,000, you can find a 1ct lab-grown diamond engagement ring in your choice of metal and setting style. This price point represents the most popular budget for lab-grown diamond engagement rings — genuine luxury without compromise.

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

Halo rings with a 1ct natural diamond start from £4,416

Natural diamonds at 1ct are priced from £2,386 for the diamond alone. Combined with a halo setting, the total exceeds your £2,000 budget.
