{"product_id":"zinkenite","title":"ZINKENITE","description":"A fine specimen of the sulphosalt Zinkenite, forming an array of acicular bladed metallic grey crystals richly aggregated over red-brown Goethite replacing Siderite crystals.  This miniature is from the Siderite lenses in the outcrops to the north of Saint-Pons village in Provence-Alpes-C'te d'Azur, France, a locality about 22 km west of the border with Italy.  Zinkenite, a lead antimony sulphide, is classed as a sulphosalt due to the presence and association of antimony (Sb) and sulphur (S).  The lath-like crystals measure up to over 1 cm and richly line a V-shaped open cavity.  Although the Zinkenite is totally stable and well anchored to the matrix, it is also delicate and friable and requires careful handling, a point to note.  This is a lovely example of Zinkenite from the Saint-Pons outcrops, enhanced by the contrasting Goethite pseudomorphs.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781509423439,"sku":"CC7882","price":740.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC7882_3b015b71-1af7-4ef0-99a3-a9692926d801.jpg?v=1783992186","url":"https:\/\/crystalclassics.co.uk\/products\/zinkenite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
