{"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":57781138587983,"sku":"CC21196","price":592.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC21196_bd9567b3-c53c-44d5-8c55-a5fef3f7aeb2.jpg?v=1783978999","url":"https:\/\/crystalclassics.co.uk\/products\/hausmannite-2","provider":"Crystal Classics UK","version":"1.0","type":"link"}
