Natural Black Tourmaline

We specialize in unheated and untreated real black tourmaline that was mined in the earth! Black tourmaline crystals are mined today at many locations worldwide. These natural black tourmalines are mainly used for metaphysical purposes, however black tourmaline does also have some very interesting scientific uses as well. Black Tourmaline is naturally pyroelectric, which means that a black tourmaline can produce an electrical charge when it is subjected to a change in temperature.

A piezoelectric current can also be generated when pressure is applied to a natural black tourmaline.

Metaphysical sources say that black tourmaline can defend against negative energies, and that it gives protection against negativity from other people as well as protection against negative energy from both electrical fields & magnetic fields.
