{"product_id":"calcite-125","title":"CALCITE","description":"This wonderful group of dark chocolate brown nail-head Calcite crystals is from the P?'bram Mining District in the Central Bohemian Region of the Czech Republic.  The crystals cover a core of massive crystalline colourless, white and brown Calcite and forms a range in crystal size from just a few millimetres across to one measuring 3 cm along an elongated face!  Certain orientated prism faces have a dusting of micro-crystals of either Pyrite or Chalcopyrite.  The nail-head crystals have a bright glassy lustre and are likely coloured by inclusions of finely disseminated Hematite.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781124104527,"sku":"CC20243","price":629.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC20243_93bc6f20-ebb2-4173-80b4-33a6e9191e3e.jpg?v=1783977948","url":"https:\/\/crystalclassics.co.uk\/products\/calcite-125","provider":"Crystal Classics UK","version":"1.0","type":"link"}
