Diamond Cut

The cut of a diamond is graded from ideal through to poor. The quality of the cut is determined by percentile proportions and the angles used to shape a stone. Having a well cut diamond is essential to the brilliance, fire and scintillation of a diamond. Brilliance refers to the return of light within a diamond. If a diamond is cut too shallow or too deep, the return of light will be lost inside a diamond or "leaked" out through poorly angled facets. Fire is the term used to describe flashes of colour resulting from spectral separation or dispersion of white light into rainbow flashes. Fire is heavily affected by the crown and other facet angles. Scintillation is often thought of as contrasting dark and brightness that alternates from facet to facet and attracts our eyes as the diamond, the illumination or the observer moves. The Gemological Institute of America (GIA) defines scintillation as "flashes of light reflected from the crown" - in other words, sparkle.
