{"product_id":"marcasite-12","title":"MARCASITE","description":"Marcasite crystals form a roughly 3.5 x 3.6 x 2.7 cm ex-matrix cluster from Cap Blanc-Nez in France.  Cap Blanc-Nez, situated 13 km east of the centre of Calais, is a coastal outcrop where the high chalk cliffs meet the English Channel.  The Marcasite forms both equant and flattened pyramidal crystals to just over 1 cm, all with a bright metallic lustre.  All crystal faces tend to have a smooth band adjacent to their face-edges, then become covered in epitaxially aligned equilateral triangular growth patterns.  A superb nodular group of wonderfully developed Marcasite crystals.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781134131535,"sku":"CC21008","price":259.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC21008.jpg?v=1783978801","url":"https:\/\/crystalclassics.co.uk\/products\/marcasite-12","provider":"Crystal Classics UK","version":"1.0","type":"link"}
