More Sparkle, More Fire and More Beauty
Beauty
The beauty of a jewel is determined by its colour, brilliance, "fire" and
lustre.
Brilliance
Brilliance is a jewel's ability to
return the white light to the viewer. It is created by cutting designs and
is measured by its refractive index. Moissanite has an RI of 2.65 - 2.69
which is higher than diamond's RI of 2.4.
Fire
Fire, or dispersion of light - is the breaking of light into the spectrum
of colours. It also refers to the rainbow colours that you see in a jewel
under lights.Moissanite has 2.5 times more fire than a
diamond.
Lustre
Lustre is the amount of light that is reflected back to the viewer from
the surface of the jewel. Moissanite's lustre rating of 20.4% is greater
than a diamond's rating of 17.2%.
Durability
The durability of a jewel is determined by its hardness, or resistance to
scratching, and its toughness, or resistance to chipping or cleaving.
Moissanite is second hardest jewel to diamond and is harder than sapphire
and ruby.
