Asscher Cut Engagement Rings in 18K Yellow Gold Under £5,000

The Asscher cut is a square step-cut diamond with deeply cropped corners that create an almost octagonal outline. Its concentric square facets draw the eye deep into the stone, producing a mesmerising windmill pattern. Invented in 1902 by the Asscher Brothers, it remains one of the most distinctive and collectible diamond shapes.

Warm, timeless, and universally flattering. 18K yellow gold contains 75% pure gold and has a rich, warm tone that has been the traditional choice for fine jewellery and engagement rings for centuries. Its natural colour will never fade or require re-plating.
