Siderite and Chalcopyrite
Availability: 1 in stock
From the find about 8 years ago, I considered these instant classics. The combination of prominent siderites set amongst bright brassy chalcopyrites makes for a dramatic display piece. One broken siderite I can find, thus the very reasonable price.
