    Meet the 6-carat square-cushion CVD lab-grown diamond—an ethical marvel that mirrors nature’s finest, minus the mine. Graded G for color, it presents a near-colorless face-up that rivals top-tier natural stones. Internally flawless to VS1 clarity, it is eye-clean and free from distracting inclusions, ensuring uninterrupted light return and fire. Cut to ideal proportions, the cushion facets act like tiny mirrors, unleashing brilliance that scores identically to earth-mined diamonds on refractive index (2.42) and dispersion (0.044). With a Mohs hardness of 10, it resists scratching for lifetime daily wear—just like its natural twin. The key difference? Zero mining footprint and full traceability, certified by IGI.
