Black Tourmaline is one of the most popular metaphysical stones and is one of the key crystals for a healing kit. The mineral name is Schorl. It is an igneous rock that mostly forms in granites and granite pegmatites. It can also form in some high temperature hydrothermal veins and metamorphic rocks.

Except for in thin section, Black Tourmaline is always a solid black. Unlike other tourmaline minerals, it is never translucent or transparent in its natural crystal form. It has a distinctive appearance with glossy long striated crystals. This structure and its other properties generate a strong piezoelectric effect, with electrically charged poles at the crystal’s poles. It is also pyroelectric, generating an electric charge through temperature changes. As a result, Black Tourmaline is a highly protective stone, able to block, repel and transmute negative energies.

You can use Black Tourmaline to remove negative energies within a physical space or emanating from another person. Black Tourmaline cleanses, purifies and transmutes dense negative energies into higher positive vibrations. It is used to protect against electromagnetic radiation (for example, from mobile phones and computers). It is also used for other disturbances and noise sensitivity. This makes it a recommended stone if you must live or work in a challenging or uncomfortable space.

Black Tourmaline has a calming effect, grounding unhelpful energies into the earth.
