schörl

Schörl is the black opaque variety of tourmaline. Tourmaline is a complex borosilicate mineral group with a hexagonal crystal structure. Schörl is the most common gemstone tourmaline and is found in a wide range of geological environments, including igneous, metamorphic, and sedimentary rocks. Its black color is primarily due to the presence of iron. While often considered a less desirable gemstone due to its opacity and color, schörl can be used in jewelry and for decorative purposes. It is also sometimes used in the manufacturing of electronics and in radiation shielding applications. In metaphysical beliefs, schörl is often associated with grounding, protection, and absorbing negative energies. It is found globally in numerous locations, with significant deposits in Brazil, Africa, and the United States. The hardness of schörl is 7 to 7.5 on the Mohs scale, making it relatively durable. When cut and polished, it can exhibit a vitreous luster. Despite its commonality, schörl remains a mineral of interest for both geological study and its practical applications.
