ID: CC15598
An outstanding specimen of superbly crystallised Franckeite with Zinkenite very richly encrusting a largely hidden matrix of Stannite, probably intermixed with Franckeite and Zinkenite.  This specimen is from the Itos mine within the confines of Oruro City, Oruro Department, Bolivia.  Itos is a large silver-tin mine and is considered to produce the world’s finest specimens of Franckeite.  Franckeite, a complex lead tin antimony sulphosalt, covers the specimen as dense sprays of metallic silver spear-shaped crystals, with an overall crinkled appearance.  The Zinkenite, lead antimony sulphosalt forms rich mats and sprays of very fine acicular crystals.  The Stannite, a copper iron tin sulphide, forms a massive mid-grey matrix which is tarnished to metallic blues, blue-greens and lilac.  A magnificent specimen of these rare species.
