Apatite is this beautifully electric blue stone made with the same chemical constituents that make up our bones and teeth: calcium and phosphorous.  So it's a good stone to have to help build the bones.  Like tourmaline, it helps ward off radiation and negativity but isn't as potent as tourmaline.  The stone helps those who have intrinsic negativity in their relationship to life.  

Hold a sphere during meditation to bring focus to negativity with the intention to clear it.
