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.

The solitaire is the purest expression of an engagement ring — a single diamond held aloft by a minimal setting, letting the stone speak entirely for itself. Solitaire settings have been the most popular engagement ring style for over a century, prized for their timeless simplicity and the way they showcase the diamond without distraction.

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.
