Black Tourmaline

Black tourmaline, also known as schorl, belongs to the tourmaline family, a group of boron silicate minerals renowned for their diverse colors and complex crystal structures. This gemstone is primarily composed of aluminum, iron, silicon, and traces of other elements, which contribute to its distinctive black hue. Formed deep within the Earth's crust under high-pressure conditions, black tourmaline crystallizes in elongated prismatic shapes, often exhibiting striations and a glassy luster.
