Glowing Metal Substance

I'm really getting sick of this ad on the radio for some jewelry store that I can't remember (great ad effectiveness there) that says something like "only gold glows". Not to be a stickler but I'm pretty sure that gold has no luminescent qualities of any kind. It drives me crazy when these guys over sell stuff like this. Gold is a precious metal, that, in my opinion, is relatively worthless when you consider that the fakes look just as good and cost a fraction of the amount. The technology behind the fakes are so advanced that there is no reason to buy the real stuff because no one can tell anyway. The gold chain needs to be broken. As I said in an earlier post, our overpricing of worthless things and ignorance for more important aspects is going to bite us someday. That is not to say that I'm without fault in this but, we do need to rethink things as a society.
