What's the deal with diamond fluorescence?
We really don’t mean to sound non-committal on this one, but for the most part fluorescence in a diamond is neither good nor bad. The truth is that most people won’t even perceive it. Some people can do it, but for the most part fluorescence in a diamond will impact your life about as much as dressing on someone else’s salad.
Bottom line, anything under ‘medium’ will make zero difference to the quality of the diamond. Even if you find a stone that has ‘very strong’ fluorescence, this doesn’t mean that the diamond will be anything other than fabulous. It just means that you need to be aware of how that fluorescence might affect the look of the stone (but probably won’t).
So when is fluorescence a problem?
Fluorescence in a diamond can impact the color in very rare cases. The good news is that this mostly involves making the stone appear whiter. This happens in lower color grades, where the blue of the fluorescence actually negates the yellow hue of the color in the stone, making it appear whiter.

In terms of the transparency of the diamond however, things can be trickier. Sometimes fluorescence in a diamond can cause the stone to look ever-so-slightly milky or hazy. Some people don’t notice this at all, some notice it immediately, while others will only spot it in certain kinds of lighting. The golden rule is to examine the stone thoroughly before you buy.
