The Brilliance & Performance of the Diamond
Cut is a measure of a diamond’s appearance, the combination of brightness, fire and scintillation. Cut also encompasses the craftsmanship of polish and symmetry.
Polish is the quality of a diamond’s surface condition.
Symmetry refers to the exactness of the shape of a diamond and the symmetrical arrangement and placement of the facets.
The GIA Cut Scale ranges from Excellent to Poor.
GIA provides a cut quality grade for standard round brilliant diamonds that fall into 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 or 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.
