{"product_id":"cafarsite-1","title":"CAFARSITE","description":"Cafarsite, named after the presence of calcium, iron and arsenic within its chemistry, was first described in the 1960s from Wanni Glacier (Wannigletscher) near Monte Cervandone on the Swiss\/Italian border and has only been reported from a handful of localities, nearly all of which are in the European alps. This miniature specimen from the superb systematic collection assembled by brothers Martin and Michael Günther (1951-2007 \u0026amp; 1956-2021) is from Mt. Cervandone on the Italian side of the border. It features many well-formed dark brown octahedral to cubo-octahedral Cafarsite crystals on matrix. The two main crystals are 4.5 and 4 mm across but there are many others sub-1 mm in size. A fine example of this alpine rarity.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781192589647,"sku":"CC27593","price":185.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC27593_8e8daad4-46cc-4bba-9066-e7c0a7e4e985.jpg?v=1783980997","url":"https:\/\/crystalclassics.co.uk\/products\/cafarsite-1","provider":"Crystal Classics UK","version":"1.0","type":"link"}
