{"product_id":"libethenite-25","title":"LIBETHENITE","description":"The late 19th century Samuel Henson dealer label accompanying this Cornish Libethenite specimen sums things up very nicely: \"very large xx\" - xx meaning 'crystals'. Phoenix United mine is well-known to have produced the largest Libethenite crystals in Britain during the latter years of the 19th century and these two crystals on a miniature specimen are considerable in size (1 and 0.9 cm). Henson's address as 277, Strand, London, dates his label to between 1878-1888. Neither crystal are entirely complete but do show the classic octahedral form. Ex Kay Robertson collection (with label and photographed by Rock Currier in 1973 - see Mindat.org), and ex. U.S. National Museum (Washington A. Roebling collection). A rare and extremely desirable Cornish classic.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781313536335,"sku":"CC43202","price":1110.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC43202.jpg?v=1783986372","url":"https:\/\/crystalclassics.co.uk\/products\/libethenite-25","provider":"Crystal Classics UK","version":"1.0","type":"link"}
