Radiant Cut Solitaire Engagement Rings in 18K White Gold Under £1,500

White gold solitaire delivers the same bright, modern look as platinum in a lighter, more affordable package. The neutral white metal lets the diamond take centre stage while the 18k gold ensures lasting quality.

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.

Bright, modern elegance at an accessible price. 18K white gold contains 75% pure gold alloyed with white metals such as palladium or silver, finished with a rhodium plating for a bright, reflective white appearance. It offers the elegant look of platinum with a lighter weight.

The £1,000–£1,500 range opens up a wonderful selection of lab-grown diamond engagement rings with larger centre stones and more setting options. This is one of the most popular budget ranges for couples choosing lab-grown diamonds.

White gold solitaires offer the most accessible entry to a premium white-metal engagement ring.
