Radiant Lab-Grown Diamonds
The radiant cut takes the cropped-corner outline of an emerald and fills it with brilliant faceting, producing intense fire in a rectangular or square silhouette. It was designed in the 1970s specifically to bridge the two families.
Because the faceting scatters light so effectively, radiants mask colour and inclusions well, which makes them one of the better shapes for stretching a budget. Lab-grown diamonds are chemically, physically and optically identical to mined stones, certified to the same standards and typically 60-80% less per carat. Our lab-grown diamond guide covers the detail. Compare it with every other outline in our diamond shapes guide, and get to grips with what actually drives price in our diamond 4Cs guide. All our stones carry independent laboratory certification and transparent pricing, and our London team will talk you through any of them with no obligation.
