Chalcopyrite is the most important copper ore on the earth today. Ores are a type of rock that contain minerals that are extracted and refined for use in a variety of ways. Often confused with pyrite, chalcopyrite actually is less brittle and rarely comes in crystalline form in comparison to pyrite. It is often referred to as yellow copper due to the high quantity of copper it contains. This specimen is of a tarnished variety, which creates a fabulous multi-colored metallic luster. This is definitely going to benefit you if you need a new unique-looking mineral to show off in your science classroom or your home collection!
