Cut

Diamonds come in many shapes, and although the cut is often thought about in terms of the diamond’s shape, the cut grade is really about how well a diamond’s facets interact with light.  

The stone’s cut determines a diamond’s sparkle and brilliance. The diamond’s cut is crucial to the final beauty and value of the stone. How a diamond interacts with light creates desirable effects such as:

Brightness 

Internal and external white light reflected from a diamond

Fire

The scattering of white light into all the colors of the rainbow

Scintillation

The amount of sparkle produced, and the pattern of light and dark areas caused by reflections within the diamond

Of all the diamond 4Cs, the diamond’s cut is the most complex and technically difficult to analyze.
