Fluorescence in diamonds
The world of diamonds and precious stones seems to be expanding, with new characteristics we didn't know before. That's why we want to share everything about diamond fluorescence with you: how it happens, what it means, and much more.
Fluorescence in diamonds is a characteristic that is present in between 25% and 30% of the diamonds in the world.
Fluorescence makes them emit a glow, usually in a bluish tone, when exposed to ultraviolet light; yes, this will only occur when they are exposed to a "black light," so this effect is not visible to the human eye.
Why does this happen?
Diamonds exhibit this characteristic due to traces of boron during the crystallization process; however, this characteristic is neither good nor bad, it is simply something that some diamonds possess.
Fluorescence doesn't add to or detract from the value of your diamond. It's now considered an added characteristic. This factor can enhance the perceived color of HK-grade diamonds. Diamonds in this category typically have a faint yellow tint which, when combined with medium or strong blue fluorescence, makes them appear whiter.
In rare cases, high levels of fluorescence can make stones appear whitish or hazy, although for the most part, fluorescence does not affect their beauty or brilliance. Diamonds are not the only stones that can exhibit this phenomenon; fluorescence also occurs in stones such as sapphires, rubies, and others.
The best way to know if your stone has fluorescence is by checking its certificate; there you will find the specifications and the exact size of your stone.
