Bornite

Imported from Mexico, this mineral is a gem grade quality specimen that is also known as peacock copper. When you flash the mineral in the sunlight you can see a blue-purple base color with flashes of red, yellow, gold, and orange. It can be used in mineral tests as well as an excellent example of a mineral that has been altered with an acid wash.
