They have this vibrational energy that scientists can't really explain (which has as much input as you invest). But let's talk other worldly.
My favourite is black tourmaline, great for negative thoughts, electrical equipment, back problems, protection from negative entities. Ancient magicians used to use them. (but 100 years of science covers all? no but it will in time )
Buy one and keep it in your pocket. Or not. =)
