Cut should not to be confused with Shape.
Diamond cutting techniques have been refined since the fifteenth century when master craftsmen
passed down their art form from generation to generation. Today, the finest diamond cutting
still occurs in the hands of a skilled craftsman. The skill and experience of the diamond cutter will
determine the stone's brilliance and scintillation. If these cutting factors fall below standard, the
appearance of the diamond will be adversely affected.
If the diamond is cut with just the right proportions and at certain precise angles, the stone's
ability to reflect and refract light will be maximized. When a round diamond is cut to ideal proportions,
light will bounce freely within the diamond, and reflect back out of the crown without escaping through
the opposite side or the bottom of the stone. The cut, polish and to what proportions and symmetry,
are the factors that determine the life, brilliance and dispersion of the diamond.

| When a ray of light touches
the surface of a diamond, part of the light is reflected back,
this is external reflection. |
|
The rest of the ray penetrates
the stone and is then reflected toward the center of the diamond.
This is known as refraction.
|
|
The ray of light is reflected
to the surface, where it is seen as the colors of the spectrum.
This is known as dispersion. |
