Fluorescence in a diamond

“For some higher-color stones, fluorescence gives the stone a milky white appearance , which greatly lowers value.

To understand this, we first have to understand what is fluorescence and how it effects the quality of diamond.

Fluorescence is the property of diamond , which makes it glow when it is kept under a UV ( Ultra Violet ) light. Fluorescence in a diamond is judged based on the intensity of the glow when it is kept under a UV light.

The grades for Fluorescence starts with None, which means no Fluorescence and as the intensity of Fluorescence increases the grades change from Very slight to Very Strong.

Fluorescence in a diamond is considered an undesirable property. Only None Fluorescence in a diamond is considered desirable, even the slightest hint of fluorescence lowers the quality of a diamond. When you decide to buy a diamond that has a higher color such as D E F (COLORLESS), you should also make sure that the diamond you chose has flurorescence grade of “ NONE”. 
Generally, the higher the quality and price per Carat, the more fluorscence lowers value. (International trade magazine Rappaport)
