For the most light, the round brilliant is the best cut for moissanite in our ray traces. It returns the most light of the ten classic shapes: brilliance 86 out of 100. The cushion (74) and the trilliant (71) come next. Fire scores are high in every shape, 92 to 97 out of 100.

Why
Most classic shapes were designed for diamond. Moissanite bends light more than diamond, so diamond angles do not send its light where the design intends. Its dispersion is more than twice diamond's, so every shape shows strong fire.
Of all 37 cuts we measure in moissanite, our own DG-M5 returns the most light: brilliance 98.
