Bright shiny group of pyrite crystals from the classic Colorado pyrite location. These main crystal in the group is up to 4.2 cm on edge. All of the crystals have highly reflective faces with striations, typical for the location, along with nice sharp edges. Minor edge wear present on some of the edges. With the mines closed, these pyrites have become highly desired and really good ones are more and more difficult to obtain. This is of incredible quality for the locality!
