{"product_id":"calcite-with-pyrite-3","title":"CALCITE   with PYRITE","description":"This superb miniature Calcite from the P?'bram Mining District in the Czech Republic, composed of multiple generations of mineral deposition, each phase manifesting as a different habit, colour, and lustre.  Formed around a central core of granular sooty-black sulphides or Mg\/Mn minerals, the first phase of calcite forms scalenohedral 'dog-tooth' crystals to over 2 cm tall that radiate outward hedgehog-like fashion.  These have then been coated in dull brick-red Calcite micro-crystals with a matt lustre then followed by burnt candy-red lustrous Calcite crystals, all approximately 1 mm in length and aligned epitaxially to the scalenohedral major axis.  A little Pyrite is also attached.  A beautiful and fascinating Calcite from P?'bram.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781029011791,"sku":"CC19696","price":1850.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC19696_6483fef3-a5ae-4585-ad3b-a2f6b558dc80.jpg?v=1783977018","url":"https:\/\/crystalclassics.co.uk\/products\/calcite-with-pyrite-3","provider":"Crystal Classics UK","version":"1.0","type":"link"}
