The black tourmaline stone is scientifically called Schorl, which makes up about 95% of all natural tourmaline present on Earth. Schorl is not the only tourmaline species: there are other tourmalines as well which are found in different colors. This mineral can be formed via a variety of geological processes. Some of the processes through which black tourmaline can be formed are as follows. The black tourmaline can be formed via magmatic activity where it crystalizes from molten rocks. Or it can originate from hydrothermal processes where extremely high-temperature mineral-rich fluids deposit the Black Tourmaline crystal in cavities and fractures of the host rock.
