A chalcopyrite (copper ore) disc sits atop a disc of copper. The copper disc sits atop a silver disc. Set on top of a simple silver band, it's metal all the way down... at least until you get to your finger.

Chalcopyrite is a type of copper ore typically found near sites of ancient hydrothermal activity. Since copper is one of its main components, this is a stone that can tarnish over time (to a beautiful iridescent purple color!) and is mildly electrically conductive.
