Square Radiant Lab-grown Diamonds
The square radiant is the radiant's compact sibling: cropped corners, brilliant faceting, and a near-square outline that sits somewhere between a princess and a cushion in character. It is a strong choice for a solitaire that needs to look substantial.
The brilliant faceting is forgiving of colour and inclusions, so budget generally goes further here than in a step cut. 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.
