Very curious siderite pseudomorph after calcite. Well defined rhombohedron totally replaced (by perimorphic processes) by a new generation of small siderite crystals. This specimen is perfect to show different siderite generations. Really interesting and huge size sample. THE MAIN CRYSTAL IS: 5,4 x 3,8 x 3 cm.
