Carlsbad, Calif.--In an effort to educate the public about ultraviolet fluorescence in diamonds, the Gemological Institute of America (GIA) will include extra information about the phenomenon in every grading report that carries a diamond-fluorescence description of medium or stronger.

There are two types of luminescence: fluorescence and phosphorescence. Fluorescence is the process of absorbing and re-emitting light on a timescale of about 10-8 seconds while phosphorescence processes are much slower, taking about 10-3 to 1 second to occur (even longer lifetimes are possible).
