| fluorescence |
An effect that is seen in some gem-quality diamonds when they are exposed to long-wave ultraviolet light (such as the lighting frequently seen in dance clubs). Under most lighting conditions, this fluorescence is not detectable to the eye. However, if a diamond is naturally fluorescent, it will emit a soft colored glow when held under an ultraviolet lamp or "black light. ...

The property in many diamonds that makes them glow in an environment rich in ultraviolet light. Diamonds can fluoresce in a number of colors, but generally all but blue are to be avoided. Faint to medium fluorescence is rarely detected under ordinary lighting conditions. Strong or very strong fluorescence may make a diamond appear

| fluorescence |
A glow, usually of a bluish color, which emanates from certain diamonds when exposed to ultraviolet light. Strong fluorescence should be avoided, but faint fluorescence usually does not affect the appearance of a diamond. In fact, faint or moderate blue flourescence is preferred by some customers because it can make a less expensive yellowish color appear more white or colorless in daylight.

| fluorescence |
Fluorescence is a form of lumination that is created when a diamond is exposed to low or high wave ultraviolet radiation. Faint fluorescence will rarely detract from a diamond's beauty and cannot normally be seen or separated by the naked eye. Strong fluorescence can sometimes improve the appearance of diamonds that possess colour.
