Domeykite is a special kind of mineral that's made mostly of copper and arsenic. Imagine it like a natural rock that has these two elements mixed together! It's usually found as bumpy, irregular lumps rather than shiny, perfect crystals.
This mineral is quite heavy and has a cool metallic look, like tin or steel. It's also pretty hard, but you could scratch it with a knife. When you find it, it might look white or gray. Over time, it can change color to a brassy yellow or even show a rainbow shimmer!
Domeykite was first discovered way back in 1845. It was found in some mines called Algodones in a place called Coquimbo, in Chile. A scientist named Wilhelm Haidinger gave it its name. He named it after a famous Polish mineralogist (that's a scientist who studies minerals) named Ignacy Domeyko.
