{"product_id":"psilomelane","title":"PSILOMELANE","description":"The P?'bram Mining District covers a wide area and Vran?ice is a village within it, around which several mines operated until 1990.  This miniature is a most attractive example of Psilomelane, what is now considered an obsolete name for hard black manganese oxides but is a well-known descriptive term still in use with collectors.  Silver grey botryoidal Psilomelane spheres averaging 1 to 2 mm diameter and occasionally a little larger, cover a white and reddish-pink massive Calcite matrix.  The Psilomelane tends to have a matt to slightly satin lustre and several mounds are dusted with brassy golden micro-crystallised Pyrite.  Also scattered over the surface are rare translucent dull apricot nail head Calcite crystals.  A very good example of manganese mineralisation from P?'bram accompanied with the pervious collector's card label.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781029830991,"sku":"CC19721","price":925.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC19721_aefaabd1-d7ed-424a-84dc-64e95793d6f5.jpg?v=1783977059","url":"https:\/\/crystalclassics.co.uk\/products\/psilomelane","provider":"Crystal Classics UK","version":"1.0","type":"link"}
