Radiant Cut Solitaire Engagement Rings in Platinum Under £4,000

Platinum solitaire is the most refined combination in engagement ring design. The purest precious metal holding a single diamond — nothing more, nothing less. This pairing has defined the engagement ring category for over a century.

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.
