Precise artistry and workmanship are required to cut a diamond so that its proportions, symmetry and polish return the maximum amount of light possible. For many people, this is the most important of the 4Cs because it determines the beauty of a diamond. Whereas two diamonds may have the same clarity, colour and carat weight, cut is what determines whether or not one is superior to the other.

The GIA Grading Scale for Diamond Cuts

The Gemmological Institute of America (GIA) has a cut grade that determines how well a diamond sparkles. It evaluates:

  • How the diamond appears when viewed face-up based on the attributes of brightness, fire and scintillation
  • How well the diamond was designed to ensure durability and optimal weight
  • The quality of the workmanship or craftsmanship that went into aligning and polishing the diamond’s facets
