{"product_id":"greenockite-with-prehnite-and-pumpellyite","title":"GREENOCKITE with PREHNITE and PUMPELLYITE","description":"An outstanding crystal of Greenockite (cadmium sulphide), extremely large and well formed for the species, measuring 7 mm long and nestling amongst crystals of colourless-milky Calcite and pale apple-green Prehnite to 0.4 cm scattered throughout.  This specimen is from the Andesite quarry at Kreimbach-Kaulbach in Rhineland-Palatinate, Germany, renowned for its amazing Greenockite crystals, but closed since 2014. The Greenockite forms a gently curved acorn or beetle-shaped crystal with a finely striated surface like brushed silk with a metallic lustre. Its colour is the typical toffee-orange normally associated with Greenockite. Strewn across much of the specimen are sub-mm botryoidal Pumpellyite crystals as sooty-black\/very dark green micro-spheres. This superb Greenockite is a wonderful location piece and is a high ranking specimen for its species. Ex Professor Werner Paar collection.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545188716719,"sku":"CC20506","price":7500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC20506.png?v=1770377352","url":"https:\/\/crystalclassics.com\/products\/greenockite-with-prehnite-and-pumpellyite","provider":"Crystal Classics","version":"1.0","type":"link"}
