Fluorescence
What is Fluorescence?
Fluorescence is the visible light emitted when a diamond is exposed to ultraviolet (UV) light. Long-wave UV is an essential component of daylight. Approximately 1/3 of all diamonds exhibit some degree of fluorescence. The most common fluorescence is blue as seen below. The diamonds below appear the same under normal lighting conditions (bottom row) but when exposed to UV (top row) the characteristic is apparent.
In rare cases of extreme fluorescence diamonds may appear slightly hazy, but in most categories fluorescence is often considered to improve the appearance in normal daylight.
Fluorescence is defined by the following terms:
None
Faint
Medium
Strong
