{"product_id":"naumannite-1","title":"NAUMANNITE","description":"For rare species collectors interested in historic specimens from Type Localities this miniature specimen should get pulses racing. Not only is an exceptionally rare example of Naumannite from the Type Locality at Tilkerode (Abberode) in Harz, Saxony-Anhalt, Germany but it comes with a very early handwritten label recording this. Naumannite was first described from Tilkerode in 1828 but under the name Selensilber, the name Naumannite being introduced by Haidinger in 1845. It has to be said that Naumannite is not the most aesthetic mineral species, but this specimen is about heritage and rarity, these things are simply never seen for sale. This one comes from the amazing systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 \u0026amp; 1956-2021), who were meticulous with keeping old labels.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545406263471,"sku":"CC27989","price":2000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC27989.png?v=1770389433","url":"https:\/\/crystalclassics.com\/products\/naumannite-1","provider":"Crystal Classics","version":"1.0","type":"link"}
