Diamonds are praised for their ability to exude light which createsÂ intense sparkle.Â So often a diamond’s cut is thought of as only being a shape, such as round,Â square, or emerald; however, a diamond’s cutÂ is actually about how a diamond’s facets interact with light.Â Â It takesÂ precise artistry to fashion a diamond so it’s proportions, symmetry and polishÂ deliver the ultimate return of light.
AÂ diamond’s cut is absolutely critical to the diamonds beauty and value.Â Of all the 4Cs, precise cutting is the most complex to analyze.Â Â This crucial aspect of cutting a proper diamond allows us toÂ create desirable visual effects such as:
- BrightnessÂ – internal and external white light reflected from a diamond.
- Fire – the dispersion of white light into all colors of the rainbow.
- Scintillation – this refers to the sparkle a diamond produces, a pattern of light and dark areas caused by reflections within the diamond.
The GIA’s Diamond Cut Scale for standard round brilliant diamonds in the D to Z diamond color range contains five grades from excellent to poor (excellent, very good, good, fair, and poor).
