What is the fluorescence of a diamond?
The fluorescence of a diamond is a luminous effect that some diamonds exhibit when exposed to ultraviolet light. They emit a visible light, usually blue.
If you want to know the degree of fluorescence of your diamond, you must go to a diamond dealer so that he can place your diamond under an ultraviolet lamp.
If your stone reacts to ultraviolet light by coloring, it means that it has fluorescence. If the diamond remains dark, it is not fluorescent.
The effect is comparable to that of a white shirt in a nightclub. Without ultraviolet light, no effect can be seen.
This fluorescence comes from a reaction between the energy of the light and the atoms of the diamond to ultraviolet rays. It is caused by the presence of nitrogen and other impurities in the diamond’s crystalline structure. A diamond will fluoresce, if there are traces of the mineral Boron present in the earth during the crystallization process.
