Guaranteed 100% natural Black Tourmaline not treated in any way... There are occasional mica and iron matrix in these natural black tourmaline round beads. The larger the black tourmaline, the better chance you'll find other minerals wildly growing within them. In our opinion, the interesting minerals add extra character to the black tourmaline and offer extra energies!
