Before choosing
a ring design, it is important to choose the diamond
you want. There are two important properties of diamonds-
brilliance and fire, contribute to a diamond’s
beauty.
A diamond's brilliance is:
- the fraction of the light that falls
on a diamond that the diamond returns to the eyes of
an observer
- the more light returned, the higher
the brilliance.
Diamond’s brilliance arises from
its index of refraction, which determines the angle
at which light is bent as it crosses the boundary between
the air and the stone.
A diamond's fire is:
Fire is the ability of a substance to
split white light into rainbow colors—the greater
the separation between colors, the greater the fire.
Diamond’s fire originates with its dispersion,
which is the difference in diamond’s index of
refraction for light of different colors. Diamond has
both a higher index of refraction and a higher dispersion
value than any other natural, transparent, colorless
material.
