The “Moissanite Jewel Grading Certificate” provides thorough information similar to that of diamond grading reports; such as, “Color, Clarity, and Carat Weight.” It also includes the stone’s exact dimensions, measurements, crown angles, girdle thickness, polish, symmetry, and fluorescence grade.
In our professional opinion, the true beauty of a gem is captured by the fire and brilliance created by light refractions and reflections. “Light Behavior Grade” is the certificate’s highlighting factor as it measures the “Brilliance, Sparkle, and Intensity” while providing a “Brilliancy Image” for a visual reference.
