{"product_id":"hausmannite-2","title":"HAUSMANNITE","description":"This lovely small miniature of well crystallised Hausmannite is from its type locality at Oehrenstock in the Ilmenau District of Thuringian Forest, Germany, an ancient manganese mining district.  Hausmannite is a manganese oxide and here forms typical jet-black triangular crystals averaging 3 to 5 mm on edge, although up to 1 cm.  The crystals have a bright metallic lustre and nestle in a matt granular matrix of massive Hausmannite and probable mixed manganese oxides.  A nice example of Hausmannite from Oehrenstock and ex. the Josef Clemente (1899-1987) Collection of southern Germany.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545292886191,"sku":"CC21196","price":800.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC21196.png?v=1770378592","url":"https:\/\/crystalclassics.com\/products\/hausmannite-2","provider":"Crystal Classics","version":"1.0","type":"link"}
