Tourmaline stones are natural crystals or aggregates of tiny crystals directly extracted from mines. They belong to the tourmaline family of minerals, characterized by their complex chemical composition, primarily featuring boron along with aluminum, sodium, iron, magnesium, lithium, and other elements. These blocks often exhibit various colors due to their unique crystalline structure and elemental composition. Tourmaline blocks are valued for their piezoelectric and pyroelectric properties, making them widely used in environmental protection, electronics, healthcare, and construction materials.
