Dispersion
Dispersion, refers to an optical property of gemstones whereby flashes and pinpoints of spectral colors are displayed as the stone is turned in the light.
Dispersion
Dispersion is the difference between the amount of refraction of different colours of light. White light is actually composed of light of all different colours.

Moissanite has a dispersive power nearly 2.5 times greater than diamond (0.104 vs. 0.044), which means the 'fire' of moissanite may be viewed as too excessive.
Dispersion is the ability of a gemstone to separate light into its component colors; that is, the quality of passing different wavelengths of light at different velocities.
