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.

Side stone settings feature smaller diamonds set along the band, adding sparkle and visual interest that draws the eye from the centre stone outward. Popular configurations include pavé, channel-set, and shared-prong designs.

Under £2,000, you can find a 1ct lab-grown diamond engagement ring in your choice of metal and setting style. This price point represents the most popular budget for lab-grown diamond engagement rings — genuine luxury without compromise.
