Asscher Cut Lab-Grown Diamond Engagement Rings in 18K Yellow Gold Under £3,000

Yellow gold with a lab-grown diamond creates a warm, vintage-inspired look at an accessible price point. The traditional warmth of yellow gold paired with the modern value of lab-grown creates a ring that honours heritage while embracing innovation.

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.
