White Fluorescence in Diamonds

Diamond fluorescence, is the effect that ultraviolet (UV) light has on a diamond. When you stand under an ultraviolet light or blue light, sometimes you can see your whites get brighter or your teeth appear to glow under these lighting conditions. This is the same effect the diamond has under UV rays. Fluorescence is the visible light that a diamond emits when it is exposed to the UV rays.

On a GIA Diamond Grading Report, fluorescence refers to the strength, or intensity, of the diamond’s reaction to long-wave UV, an essential component of daylight. The light emitted lasts as long as the diamond is exposed to the ultraviolet source of light.

There are three elements that can be absorbed by the diamond that will cause fluorescence:




It is rare to come access a white fluorescence stone, this Liberian rough diamond has a white fluorescence glow. White fluorescence usually does not affect the value of the rough diamond. Other fluorescent rough diamonds can lose up to 80% of their value due to fluorescence or phosphorescence.
