{"product_id":"allophane","title":"ALLOPHANE","description":"Wheal Hamblyn, near Bridestowe, Devon.  Please note, this enigmatic mine has two spellings of almost equal association with the locality: 'Hamblyn' according to F. W. Rudler and 'Hamlyn' reported by A.K. Hamilton Jenkin.  Unfortunately, this mine is not recorded in H.G. Dines' \"The Metalliferous Mining Region of South-West England\".  The Allophane is also associated with spherules of Malachite and ferruginous Quartz.  This is a rare Devonshire specimen from this little known copper mine on the edge of a Limestone Quarry near Bridestowe, about 9 km south-west of Okehampton.  It is not certain which quarry the mine is near, as there are two near Bridestowe, and one a little further away.  If only National Grid References had existed in the old days!","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781464662351,"sku":"CC5292","price":200.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC5292_e44ad430-7770-4de1-b681-5f5445befa3a.jpg?v=1783989784","url":"https:\/\/crystalclassics.co.uk\/products\/allophane","provider":"Crystal Classics UK","version":"1.0","type":"link"}
