Pyrite with Siderite

Very bright, light metallic golden Pyrite crystals are clustered and scattered over intergrown light brown crystals of Siderite from Hüttenberger Erzberg in Carinthia, Austria. The Pyrite crystals measure to 1.4 cm and display excellent crystal habits; many forming pyritohedron’s with further modifications. Cuboctahedral crystals also occur, principally in the octahedral form, truncated by small faces representing the cube. All the Pyrite, although smooth and highly lustrous, has a frosted texture on close inspection, a result of micro-crystallised surface patterns. The Siderite forms sharp rhombic crystals of translucent light to mid tan and sparsely scatted over these are white to colourless Calcite crystals. A stunning small cabinet specimen of Pyrite with Siderite and minor Calcite from Hüttenberger Erzberg.
