Recorded live session in which I discuss the mineral Pyrite and show beautiful examples of it from around the world. Specimens from Spain, Peru, USA and China as well as from the Netherlands show the variety of forms of Pyrite well. I pay brief attention to the related minerals marcasite and chalcopyrite.

In this video, I discuss how to distinguish between true bornite and acidified chalcopyrite.
