{"product_id":"calcite-with-pyrite-and-goethite","title":"CALCITE   with PYRITE and GOETHITE","description":"Glassy, translucent Calcite crystals cover a matrix of massive, opaque white Calcite from the Příbram mining district in the Czech Republic. The Calcite forms as complex, stepped rhombohedral crystals and as curved thin blades averaging 2 cm across; the latter usually overgrowing the former. Many of the crystals have a pale orange-tan core which imparts additional colour and interest to the specimen. Between some clusters of Calcite are small areas of modified cubic brassy Pyrite crystals of 1 to 1.5 mm and occasional hemispherical sprays of velvet-like, milk chocolate-brown Goethite.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781013119311,"sku":"CC19081","price":333.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC19081_669e97de-dc69-4a76-9d30-c9fa695a7f39.jpg?v=1783975587","url":"https:\/\/crystalclassics.co.uk\/products\/calcite-with-pyrite-and-goethite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
