Here are explanations of when fluorescence can lower a diamonds quality: HaIf the diamond only glows when exposed to ultra-violet light, then it should naturally only matter if you are someone who spends their days in dark rooms with black light lamps. In fluorescence, a material absorbs relatively high energy light such as ultraviolet and gives off a lower frequency in the visible range, making the substance unnaturally bright. I have a number of rubies from Burma that are natural and light up like a Christmas tree under UV light, like the rubies that Jeffery shared on this post. The oxidation state of an atom is a measure of the degree of oxidation of an atom. Usually these place names reflect where their discoverer worked.
