The radiant cut is the best of both worlds — the geometric elegance of a rectangular shape with the light performance of a brilliant cut. Unlike the emerald cut's understated reflections, a radiant diamond throws intense sparkle from every angle, making it one of the highest-performing shapes available. Our radiant cut lab-grown diamond engagement rings feature IGI-certified stones crafted to maximize brightness in any lighting. Set in solitaire, halo, or pave band styles in 10K, 14K, or 18K gold or platinum, each ring is custom-built to your specifications. If you want a rectangular diamond that truly blazes with light, the radiant cut is your answer.
