Lab-grown today using the same chemical structure — silicon carbide — with a refractive index higher than diamond. 9.25 on the Mohs scale. It doesn't scratch, cloud, or fade. Independently Certified Every Luhusati stone comes with a GRA certificate of authenticity. D color, VVS1 clarity — the same grading language used for diamonds, applied to a stone that earned it. Passes the Diamond Test Moissanite conducts heat at near-diamond levels. The tester can't tell the difference.
