Why Do Natural Diamonds Show Fluorescence

Why do natural diamonds show fluorescence? The phenomenon that natural diamonds emit blue, yellow and other colors after being irradiated by ultraviolet rays or other high-energy radiation sources is called fluorescence. Facts have proved that natural diamonds found all over the world will have this strange natural luminescence phenomenon, and the exact reason for this feature is still unclear.

Until today, all aspects of fluorescent diamonds cannot be fully explained. Through the general theoretical explanation of the motive of the fluorescence phenomenon, it can be seen that natural diamonds were formed billions of years later. During the formation of carbon crystals, they absorbed other trace elements and arranged in a triangular structure. Scientifically speaking, these are called "N3 color centers". When natural diamonds are exposed to ultraviolet light, these higher energies cause the internal electrons of atoms or ions in the crystal structure to transform and release energy, thereby forming fluorescence that our eyes can perceive.
