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 emerald cut is a step-cut diamond with long, open facets that create a hall-of-mirrors effect rather than the fiery sparkle of brilliant cuts. Its clean lines and geometric proportions make it the diamond of choice for those who value sophistication over sparkle. The emerald cut has deep roots in Art Deco design and remains a hallmark of refined taste.

Under £2,500, a 1ct lab-grown diamond engagement ring in platinum or 18K gold is well within reach — with budget left over for a more intricate setting style such as halo or side stone.

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