Beautiful lustrous black metallic Cassiterite crystals form an unusual multi-peaked specimen, resulting from various degrees of twinning. From the Horn' Slavkov mining district in Bohemia, Czech Republic, this ex-matrix Cassiterite is strewn with micro-crystallised minerals between the individual and twinned Cassiterite crystals. These likely include purple Fluorite, brown globular Siderite, greenish-yellow mica and creamy-white Albite. A choice Cassiterite from Horn' Slavkov.
