{"product_id":"siegenite-on-chalcopyrite","title":"SIEGENITE on CHALCOPYRITE","description":"For the collector of rare species, a nice example of Siegenite with Chalcopyrite from Victoria mine at Littfeld in Siegerland, North Rhine-Westphalia, Germany.  Like many other specimens, this was labelled as Linnaeite (not Linarite), but modern analysis has shown this to be Siegenite, a cobalt nickel sulphide, with no known presence of Linnaeite  at this locality.  Linnaeite is both a divalent and trivalent cobalt sulphide.  The Siegenite forms as slightly iridescent octagonal crystals  lining a larger vug on one side and a small vug at one end, each framed by massive and semi-crystalline Chalcopyrite.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46584655544495,"sku":"CC27825","price":400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC27825.png?v=1771851237","url":"https:\/\/crystalclassics.com\/products\/siegenite-on-chalcopyrite","provider":"Crystal Classics","version":"1.0","type":"link"}
