{"product_id":"chalcophyllite-1","title":"CHALCOPHYLLITE","description":"The Potrerillos mine in Chañaral Province, Atacama, Chile, worked a mineralized porphyry stock which intruded a sedimentary carbonate sequence of mid to late Mesozoic age.  This rich specimen of the copper-aluminium arsenate Chalcophyllite is a magnificent example of this quite rare species and covers two main areas measuring approximately 6 x 2 cm and 3 x 1.5 cm.  The Chalcophyllite forms an intergrown network of platy hexagonal crystals of its characteristic bluish-turquoise, commonly of 3 to 4 mm across.  Surrounding much of the Chalcophyllite is a dark leaf-green, micro botryoidal mineral whose identify is unknown, but it is quite possibly amorphous. The matrix in the base is criss-crossed by thin veinlets of Azurite.  A magnificent Chalcophyllite from Chile and probably dating to the 1960s.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781513552207,"sku":"CC8183","price":3701.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC8183_cf8af552-6be6-407d-862c-051d4a290db1.jpg?v=1783992369","url":"https:\/\/crystalclassics.co.uk\/products\/chalcophyllite-1","provider":"Crystal Classics UK","version":"1.0","type":"link"}
