What is diamond fluorescence?Updated 2 months ago

Fluorescence is the visible light some diamonds naturally emit when they are exposed to UV rays. It refers to the strength or intensity of the diamond's reactions to long-wave UV, which is an essential component of daylight. The light emitted lasts as long as the diamond is exposed to UV. 

Of diamonds that do exhibit some degree of fluorescence, only 10% show those strengths of fluorescence that may impact the stones appearance. It can result in a blue like colour, and in some very rare occurrences (0.2%) a milky/hazy diamond. 

Diamonds with a level of fluorescence that would impact the visual beauty of the stone would not meet our quality standards.
