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.

An engagement ring does not need to cost a fortune to be meaningful. Under £1,000, lab-grown diamond rings offer genuine sparkle and certified quality at an accessible price. At MOH, every ring in this range is handcrafted in Hatton Garden with the same care as our most expensive pieces.

A natural solitaire focuses your investment on the stone — the most enduring part of the ring.
