Chris made me a believer when it comes to magnetite and lodestone. One of the stones that I keep in my pockets when I leave the house is two nice pieces of rough lodestone, like the pocket rock sets we have for sale. Magnetite and lodestone are basically the same stone, but lodestone actually became slightly magnetic and magnetite just sticks to magnets.
Magnetite and lodestone are good for attracting what you want and repelling what you don't want...which, if you ask me, pretty much could be used in any energy work or healing application you can imagine. I like them in any grid or medicine set. I obviously like them as pocket rocks. Also, one of the best applications is that it might help you to be less effing crazy during solar flare activity. If you've ever had sleepless nights and feel all jiggy, why don't you do yourself a favor and check spaceweather.com to see if there have been geomagnetic storms. Seriously, sensitive people get whacked around by that stuff. Magnetite and lodestone help you dig more deeply into the magnetic field of the planet so you aren't getting tossed around like a feather in the wind. They are cheap too. It's worth a try!
