Augite is a dark green, brown, or black pyroxene mineral and an important constituent of igneous rocks such as basalt and gabbro. Its formal scientific history dates to 1792, when German mineralogist Abraham Gottlob Werner described and named it from the Greek auge, meaning “shine” or “luster,” referring to its reflective cleavage surfaces. Found worldwide, notable localities include Mount Vesuvius in Italy, Germany’s Eifel volcanic district, Scotland’s Isle of Skye, and Kilbourne Hole in New Mexico. In modern crystal lore, augite symbolizes grounding, stability, endurance, and practical focus
