Fluorescence

Over the past forty years, fluorescence has been a hot topic of debate for diamonds.  Although it is not as important as other aspects of purchasing a diamond, it is a good idea to at least be familiar with fluorescence if one is buying a diamond.  Fluorescence is a diamond’s inclination to give off a soft glow when under UV light, like a black light.  This is caused by the natural elements and properties of diamonds. 

Because some believe that fluorescence affects the quality of the diamond, it has affected the pricing of diamonds in some cases.  Some argue that fluorescence affects the look of a colorless white diamond and can actually enhance the look of slightly colored white diamonds. 

However, the general opinion today is that fluorescence does not actually affect diamond quality and it is exceptionally hard to see the fluorescence with an ultraviolet light.  Fluorescence can be used to one’s benefit to receive lower prices; however, since opinions are always changing, for reselling purposes, it may be beneficial to buy diamonds without it.  Overall, fluorescence is not as important as the Four C's or other aspects, but it is definitely worth thinking about.
