Fluorescence In Minerals-I

Well over 3600 mineral species have been identified at this time; over 500 of them are known to fluoresce visibly in some specimens.

Most minerals do not fluoresce when pure. It takes certain impurities in certain quantities to make the mineral fluoresce. Such impurities are called "activators". Different activators can make the same mineral fluoresce in different colors. Different minerals require different activators, and in different quantities. There are also impurities, notably ferrous iron, that can prevent fluorescence despite the presence of an activator. Because the activators and deactivators may or may not be present in any given specimen, different specimens of the some mineral (especially from different locales) may vary in color and degree of fluorescence. A common fluorescent mineral is calcite. It comes in just about all the observed fluorescent colors due to different activators. Red and pink fluorescent calcites are often activated by a combination of lead and manganese.
