What is meant by Light Performance and how is it evaluated?

The beauty of a diamond is primarily determined by the way it handles light.  Sparkle, brilliance, and fire are all effects that derive from the cut quality of the diamond - the proportions, facet alignment, and finish.  There are a number of diagnostic tools used to evaluate the key aspects of light performance such as light return, light leakage, dispersion ('fire'), scintillation, and optical precision.  Please see our diamond analytics page for detailed information on  light performance diagnostics available to the consumer today.
