1.  What makes Moissanite "sparkle"?  What characteristics of Moissanite give it such exceptional brilliance?

The Refractive Index (RI) of a gemstone is the most important physical property affecting its potential brilliance (sparkle).

With an RI of 2.65 - 2.69 Moissanite displays more brilliance than diamond (RI 2.42) or any other popular gemstone, such as ruby (RI 1.77), sapphire (RI 1.77), and emerald (RI 1.58).

2.  Will the brilliance ever fade?

No.  Charles & Colvard provides a Limited Lifetime Warranty that every Charles & Colvard created Moissanite jewel will maintain its brilliance and fire for the lifetime of the owner.

Fire (Defined as Moissanite's Dispersion)

1.  What gives Moissanite its fire?

A gemstone's "fire" is caused by dispersion - the property by which light is spread out according to its wavelengths (colors) as it passes through an object.  Moissanite's dispersion is 0.104 and can be calculated scientifically.

2.  How does Moissanite's fire compare with that of other popular gemstones?

Moissanite displays 2.4 times more dispersion or fire than diamond (0.044) and much more dispersion than ruby (0.018) and emerald (0.014).

3.  Will a Moissanite jewel ever lose its fire?

No.  Charles & Colvard provides a Limited Lifetime Warranty that every Charles & Colvard created Moissanite jewel will maintain its fire and brilliance for the lifetime of the owner.
