Chalcopyrite Chunks

$10

Want to hold a peacock in your hand? These chalcopyrite chucks are the next best thing! Listing is for one chunk. Intuitively chosen. 

Chalcopyrite is a brass-yellow mineral with a chemical composition of CuFeS2. It occurs in most sulfide mineral deposits throughout the world and has been the most important ore of copper for thousands of years. The surface of chalcopyrite loses its metallic luster and brass-yellow color upon weathering. The iridescent colors of weathered chalcopyrite are what gives these chunks their pop!
