What is Fonder Light Performance score?

Fonder Light Performance grades a diamond's light performance based on 4 parameters: Brilliance, Sparkle, Fire and Symmetry.

• BRILLIANCE is also called Light Return the amount of white light that is returned to the table of the diamond.

  When a diamond has outstanding Brilliance qualities, powerful white light is emanated from the diamond, thus making it look brighter than its actual colour grade.

• FIRE is also known as Light Dispersion. It is the dispersion of white light into rainbow colours as the light bends through the diamond.

  The beauty of a diamond with Excellent Fire, is magical and mesmerizing to behold.

• SPARKLE refers to the flashes of white and coloured light that are visible as the diamond moves.

  A diamond with high Sparkle index will appear more alive with its dazzling display of white light and coloured flashes.

• LIGHT SYMMETRY is the measure of the distribution of light throughout the diamond determined by cuts and inclusions.

  A well-cut diamond features optimal proportions for equal light distribution.
