Moissanite Carat Charts

Carat weight can appear differently across different moissanite shapes such as round brilliant, princess, pear, oval, cushion, marquise, emerald, radiant or heart. A moissanite may have a higher carat weight without appearing larger and two moissanite of the same carat weight can vary in size if one is cut deeper than the other. In other words, it is important to note that carat weight does not necessarily denote size. Sizes are shown for proportionality purposes. Images do not reflect actual carat size.

Is a Higher Carat Weight Better?

Taken by itself, carat weight does not determine a moissanite’s value. For example, two one-carat stones can vary widely in price when clarity, color and cut are taken into consideration. When that is understood, it is clear that large moissanite of peerless quality are rare.
 

“Perimade is synonymous with excellence in craftsmanship, and this is something we’ve maintained for nearly a decade.”
