The change in color of gems from radiation is a well known effect as I pointed out. It's in any good college course on solid state physics, and whole textbooks are written on the subject. Did you even read the link I gave on why this happens ? I just thought you might be interested in some background on the effect, it's not like the green magic markers effecting the sound of audio CDs or other urban myths. At any rate it's surprising that they are widely using these tools given the potential side effects, so it's worth being careful about shipping gems (or photographic film...) Heating gems that have changed color should restore their original color, though that might not be practical once they're mounted in jewelry.
