Most consumers are familiar with the 4 C's of diamonds-cut, clarity, color and carat weight, which determine the desirability price of a diamond. So how does Moissanite rate  in these areas? 

Moissanite Cut: Carefully and precisely hand-faceted each Charles & Colvard created Moissanite tm jewel is cut according to exact angles and proportions designed specially for Moissanite to maximize its brilliance and enhance its incredible fire.

Moissanite Color: Charles and Colvard expressly refrain from grading moissanite according to the popular color scale for diamonds. However, moissanite dealers and customers report that the color of moissanite compares mostly to I-J of the diamond color grades.

Moissanite Clarity: The clarity of Moissanite can be compared to a VS1 in the diamond clarity grades. Moissanite is very clean to eye clean, clarity does not vary by shape or cut. Any minor inclusion will no be visible to the eye and will be hard to find even under a 10-power loop.

Moissanite Carat Weight: Moissanite's gravity is slightly lower then diamonds, about 13% less dense. Since most jewelry is identified by carat weight, Charles and Colvard provide a corresponding mm size to a diamond equivalent weight.
