Lab Diamond Radiant

The Lab Diamond Radiant Cut is a stunning, modern choice that delivers the best of both worlds: the elegance of an emerald shape combined with the explosive brilliance of a round cut. This rectangular lab grown diamond is celebrated for its spectacular light return, often creating a dazzling "crushed ice" effect. Choosing a lab-created stone guarantees an ethical diamond origin and a superior value compared to mined counterparts. The Radiant Cut's clipped corners enhance its durability, while its shape offers a visually larger look per carat. This is a brilliant, sustainable, and sophisticated choice for modern diamond jewelry.
