Charles & Colvard expressly refrains from grading moissanite according to the popular color scale for diamonds. However, moissanite retailers and customers report that the color of moissanite compares to diamonds of I-J color.
The scientists at Charles & Colvard have determined the best cuts for each moissanite jewel shape. These cuts DO NOT correspond to popular cuts for diamonds, sapphires and other precious gemstones. Since moissanite and diamonds are fundamentally different, jewelers use different cutting techniques to maximize brilliance and clarity.
The clarity of Moissanite is clean to the eye and can be generally compared to a VS1 diamond. Clarity does not vary by shape nor size of moissanite jewels. Each moissanite jewel contains small inclusions. The most common inclusions are whitish needle-shaped structures, VS or lower in appearance.
Moissanite & Diamond Equivalent Weight
Moissanite's specific gravity is slightly lower than diamonds. Since most jewelry is sold by carat weight, Charles & Colvard provide a corresponding mm sizes and diamond equivalent weight guide. Moissanite is 13 percent less dense than diamonds.
