The cutting specifications for moissanite jewels are designed to maximize the brilliance and fire inherent in the material. To maximize the light reflecting from a faceted moissanite jewel requires the design of shapes with proportions and angles unlike any other jewel.

Using computer modeling, Charles & Colvard created proprietary designs to display the maximum light refraction based on the optical properties (i.e. fire, brilliance and luster) of moissanite jewels. A unique version of the round brilliant cut was the first shape developed applying these computer models. Recently Charles & Colvard designed new fancy shapes that eliminate dark areas commonly found in other gemstones with these fancy cuts. It is believed that these proprietary designs enhance moissanite's physical properties for the superior optical performance observed in faceted moissanite jewels.
