text: crystals and what the do.? you how crystals get rid of bad energy? and maybe sometimes good energy? well i would like to know a calcite can do..... like i would like to know what rose quartz, kyanite, amythest and tigers eye do... thankyouso much... i am a real sprirtual person. the question might better be posed, what do you think they will do for you?   the human mind and body is a very complex organism, and it's been proven over and over again that the placebo effect is extremely powerful.  if you believe that the crystals will help you get rid of unpleasant feelings or other "bad energy", then very likely they will.  the same is true of all the ones you specifically listed.
