Proustite

Cluster of Proustite crystals, complete all around with well defined, upright crystals. These are sometimes called 'ruby silvers' and show a bright cherry red color. Translucent and relatively undamaged with a couple potential contacts on the back side. Just released from an old collection. I took one shot with close overhead lighting and another with backlighting to show the translucent red color. A rare and historic specimen.
