What
we commonly call brilliance is determined by refractive index.
Brillance is a measure of how much white light is returned to
the eye.

Hardness
refers to a gemstone material's resistance to being scratched. It
is rated on the Mohs scale. A diamond has a rating of 10. Moissanite
rates a 9.25, making it the second hardest mineral known to man.
Sapphire and Ruby have a rating of 9. |
As
light travels through a gem, it separates into the colors of the
rainbow. This splitting effect is known as fire. Moissanite has
2 times the fire of a diamond. Even under candle light, it displays
an absolutely brilliant range of color.
