| Cut describes the proportions and angles
of a diamond. Many people confuse cut with the shape of
a diamond. Although nature determines the other three
characteristics, it takes a master diamond cutter to reveal
a diamond's true beauty. Diamonds are available in various
shapes including round, square, pear, heart, marquise
and oval but cut refers to the angles and proportions
of a diamond.
A well cut diamond reflects light from one mirror-like
facet to another and projects the light through the
top of the diamond. The result is a fiery and brilliant
display. Diamonds that are cut too deep or too shallow
leak light through the side or bottom, resulting in
a lackluster appearance and diminish value.

What exactly are Brilliance,
Dispersion and Scintillation?
Brilliance is the liveliness and sparkle exhibited by
a diamond. It occurs when the maximum amount of light
entering through the top of a diamond bounces inside from
one facet to another and is then reflected back to the
viewer’s eye.
Dispersion is a term that describes the flash of different
colored light coming from the interior of a diamond.
It occurs when white light is separated into its component
rainbow colors as the light is passed through the facets
of a diamond. Fire is another term used to describe
dispersion.
Scintillation describes the quick flashes of light,
resembling colorful, fiery sparks, reflected from a
polished diamond. It occurs when either the diamond,
the light source, or the observer moves. Sparkle is
another term for scintillation.
