Bronzite

ronzite is a bronze-brown to dark green mineral that belongs to the pyroxene group, specifically the enstatite-ferrosilite series, and is composed primarily of magnesium and iron silicate. This mineral is known for its metallic sheen or “schiller effect,” where light reflects off the mineral’s surface, giving it a shimmering, golden-bronze appearance that is highly sought after in decorative stones. Bronzite often forms in massive to granular habits and is found in a variety of igneous and metamorphic rocks, particularly in peridotites and serpentinites.
