Physical properties
Hardness of 3 on Mohs scale. Displays metallic luster and a distinctive iridescent purple, blue, and brassy tarnish.
Formation & geological history
Forms in hydrothermal veins and contact metamorphic zones, often associated with other copper sulfides.
Uses & applications
Extracted as a minor ore of copper and widely collected as an ornamental mineral specimen.
Geological facts
Natural freshly broken bornite is brownish-bronze; the vibrant peacock colors develop rapidly upon exposure to air due to oxidation.
Field identification & locations
Identified by its characteristic iridescent tarnish and lower hardness than chalcopyrite, commonly found in major copper-mining regions worldwide.
