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.
