{"product_id":"ferro-siderite-stolberg-harz","title":"Ferro-Siderite - Stolberg, Harz","description":"\u003cp\u003e\u003cspan\u003eUnusual pitch-black iron-rich siderite crystals (ferrosiderite) of exceptional quality, displaying remarkably sharp crystal faces and a striking metallic luster. Their intense black coloration reflects a particularly high iron content, giving these crystals a far more dramatic appearance than the typical brown to honey-colored siderites commonly known from many classic localities.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis specimen originates from a discovery made around the early 2000s near Stolberg in the Harz Mountains, Germany, a historic mining region with centuries of metalliferous mining tradition. The Harz district is renowned for its complex hydrothermal mineralization, where iron-bearing carbonate minerals such as siderite frequently occur in association with the region’s polymetallic ore veins.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eCrystals from this find are especially notable for their unusually sharp, well-developed rhombohedral forms and the rare, almost metallic sheen that enhances their aesthetic appeal. Material of this quality and color is seldom encountered, making these ferrosiderite crystals a particularly distinctive example from the Stolberg area and a noteworthy piece for collectors interested in classic Harz mineralization.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSize: 4 x 2.8 x 1.4 cm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOrigin: Stolberg, Harz, Germany\u003c\/span\u003e\u003c\/p\u003e","brand":"weloveminerals","offers":[{"title":"Default Title","offer_id":53897761456468,"sku":null,"price":22.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/2291\/1572\/files\/FullSizeRender-Photoroom.jpg?v=1772997934","url":"https:\/\/weloveminerals.com\/products\/ferro-siderite-stolberg-harz","provider":"weloveminerals","version":"1.0","type":"link"}
