Cuprite with Native Silver

An amazing Russian Cuprite specimen with a massive Wow factor!  Superb, sharp octahedral Cuprite crystals up to 2.2 cm on edge and 2.5 cm wide, stack on top of each other and, around where the crystals join, bright silver-white granular crystals of Native Silver are richly scattered.  The Cuprite, due to the large size of the crystals, is an opaque metallic mahogany-gunmetal, but over its base where the octahedral crystals are much smaller, the typical translucent cherry to claret-red colour shins through.  A wonderful and very reasonably priced specimen from the Rubtsovsk mine, which worked a volcanogenic massive sulphide (VMS) deposit in the Rubtsovsky District of Russia.
