What is Moissanite Clarity?
Moissanite clarity is a measure of the purity and rarity of the stone, graded by the visibility of these characteristics under 10-power magnification. A stone is graded as flawless if, under 10-power magnification, no inclusions (internal flaws) and no blemishes (external imperfections) are visible. At Perimade, we only accept 0.04% of the gem-grade moissanite.

Perimade Standard of Clarity
Perimade’s strict moissanite grading standards are executed with expertise, integrity and accuracy. When Perimade believes that a moissanite’s clarity is on the borderline between two grades, Perimade will always assign the stone a lower grade—never falsely inflating a moissanite clarity grade.
Does Moissanite Clarity Really Matter?
A moissanite with a poor clarity grade has multiple inclusions, which directly affects sparkle. Because inclusions hinder the refraction and return of light, the lower the clarity grade, the cloudier the moissanite will appear.
“If anything takes away from the beauty of the stone, we won’t accept it.”
—Hannah Lee, moissanite grader
