One pound mining bag of small colorful Chalcopyrite in natural mining soil.

The color is slightly more yellow than that of pyrite and often tarnished in brilliant iridescent hues which are also referred to as "peacock copper”. Chalcopyrite is a major ore of copper, and comes from the Greek words chalkos. "Copper" and pyrites, "strike fire".

Use a screen to rinse and discover these lovely colorful minerals. A nice addition to any rock and mineral collection. The stones within this bag are small in size. Hardness is 3.5-4
