Asscher Cut Natural Diamond Solitaire Engagement Rings Under £4,000

The natural diamond solitaire is the most iconic engagement ring combination in existence. Nothing compares to the simplicity of a single natural diamond, formed over billions of years, set in a minimal mount that lets nature's masterpiece speak for itself.

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.
