CALCITE, SIDERITE, SPHALERITE

A specimen with many contrasts. On a deep black but brilliant matrix of sphalerite, with complex and defined crystals, a layer of brilliant orange crystals of siderite. Accompanied by really aesthetic calcite crystal aggregates, good brilliance, translucent, formed by several rhombohedral flattened calcite crystals. Good size specimen and perfect for display. From a classic European mine. THE MAIN CRYSTAL IS: 1,8 x 1,5 x 0,8 cm.
