Chalcopyrite (or copper pyrite), looks like, and is easily confused with Pyrite, FeS2. Chalcopyrite is one of the minerals refered to as "Fool's Gold" because of its bright golden color. But real gold is a more buttery yellow and is ductile and malleable. As an ore od copper, the yield of chalcopyrite is rather low in terms of atoms per ...
Luster: Metallic. Hardness: 3.5-4. Chalcopyrite is a common copper iron sulfide mineral that is the primary ore of copper. It has a brassy yellow color and often exhibits a distinctive iridescence known as "peacock ore .". Chalcopyrite is the most common copper mineral found in copper deposits worldwide, including those in Arizona.
Chalcopyrite. Chalcopyrite is the principal source of copper. It is also the most likely source material for many other notable copper-bearing minerals like turquoise, malachite, cuprite, azurite, etc. These minerals form in the supergene environment (close to the surface) where chalcopyrite is not stable in contact with groundwater.
A botryoidal variety of chalcopyrite with an iridescent sheen was called "blister copper" by the Bristol miners. (9.7 x 7.5 x 4.8 cm) (Image courtesy iRocks) Of course, I think that's true of all rocks, gems, minerals, fossils, and examples of lapidary art. Sometimes their stories are clearly apparent and sometimes they are less obvious.
