how are diamonds cut

Understanding Diamond Cut

Diamonds are known for their ability to transmit light and shine so intensely. We often think of a diamond's cut (round, heart, oval, marquise, pear), but what a diamond cut actually means is how well a diamond's facets handle light. Precise artistic and craft skills are required to shape a stone so that its proportions, symmetry and brilliance provide the beautiful return of light only possible in a diamond.

Achieving the best cut for a diamond is reflected in the final beauty and value of the stone. And of all the 4Cs of diamond, it is the most complex and technically difficult to analyze. To determine the cut quality of the standard round brilliant diamond, the shape that dominates most diamond jewelry, Efjewel calculates the proportions of those facets that affect the face-up appearance of the diamond. These reports allow Efjewel to evaluate the best cut for a diamond by studying how a diamond interacts with light to create the desired visual effects, such as:

  • Brightness: Inner and outer white light reflected from a diamond
  • Fire: Scattering of white light into all colors of the rainbow
  • Scintillation: The amount of brilliance a diamond produces and the pattern of light and dark areas caused by diamond reflections
