Can Moissanite Pass a Diamond Tester?
Moissanite does not test as a diamond. It has an entirely different chemical composition. Moissanite is also graded differently than diamonds. Both mined and lab-grown diamonds are graded by the 4Cs — cut, color, clarity, and carat weight. Moissanite is only graded on color.When consumers buy moissanite, they choose from Premium (G-H on the color scale) or Super Premium (D-F). The clarity of moissanite is essentially perfect for each stone. Lab diamonds and mined diamonds, however, feature inclusions. They must be graded on clarity, as well as cut and carat weight.
