Diamond Cut • Diamond Cut plays a major role in the beauty and value of a diamond. Of all the diamond four “C”s, it is the most technically difficult to classify.

To determine the cut grade of a diamond you need to calculate proportions of the facets that influence the diamond's appearance. These proportions allow you to better evaluate how a diamond interacts with light. Much of the new science is referred to as “light performance“. Light performance includes the following;

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 a diamond produces, and the pattern of light and dark areas caused by reflections within the diamond

Cut grades also takes into account the design and craftsmanship of the diamond, including its weight relative to its diameter, its symmetry of its facet arrangement, and the quality of polish on those facets.
