Diamond Cut
Of the Four "C", cut may be the
most important visually. When a stone is not cut or manufactured correctly, color and clarity suffer greatly. The cut of a diamond refers not only to the shape of the diamond and number of facets, but also to the quality of the cut. A diamond with uneven or poorly proportioned facets, won’t be given the same grade of cut as an ideally proportioned and masterfully cut stone.
In the strictest definition of the term, "cut" is not the same thing as shape. A diamond's shape refers to its silhouette, for example: round, pear shape, marquis, square, emerald cut, trillion etc. However a diamond’s cut refers to the very exact mathematically determined proportions between its facets, so as much light is reflected out of the top of the diamond as possible.
The GIA Cut Scale ranges from Excellent to Poor. Gia provides a cut quality grade for standard round brilliant diamonds that fall in the GIA D-to-Z color range.

A polished diamond's beauty lies in its complex relationship with light: how light strikes the surface, how much enters the diamond, and how, and in what form light returns to your eye.
The result is a magnificent display of three attributes. Brightness is the combination of all white light reflecting from the surface and interior of a diamond. Fire describes the "flares" of color emitted from a diamond. Scintillation describes the flashes of light you see when the diamond, the light, or the observer moves.
A polished diamond's proportions affect its light performance, which in turn affects its beauty and overall appeal. Diamonds with fine proportions, symmetry, and polish optimize their interaction with light, and have increased brightness, fire, and scintillation.
