{"product_id":"calcite-on-schalenblende","title":"CALCITE   on Schalenblende","description":"A very good miniature of well crystallised, creamy-fawn translucent Calcite mostly covering a thin bed of brown and dark grey banded Sphalerite, variety Schalenblende. This specimen is from the Diepenlinchen mine at Mausbach in North Rhine-Westphalia, Germany. This was one of the most important mines in this lead-zinc ore field and was originally worked during the Roman occupation in the 2nd century AD. The Calcite forms slightly elongated rhombic crystals in the dog tooth habit, with a greasy to waxy lustre. The Schalenblende displays good banding beneath the specimen, with its upper display surface encrusted in deep clove-brown micro-crystals. The specimen is accompanied with a nice old German handwritten label in elegant copperplate script.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781031108943,"sku":"CC19769","price":259.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC19769_6e9d5d8f-9511-4b24-9a8d-aff7885aeb0e.jpg?v=1783977120","url":"https:\/\/crystalclassics.co.uk\/products\/calcite-on-schalenblende","provider":"Crystal Classics UK","version":"1.0","type":"link"}
