{"product_id":"gerhardtite","title":"GERHARDTITE","description":"A rich small cabinet-sized mass of purple-red Cuprite coated with Malachite, has a 6 cm long internal cavity richly filled with dark blue to blue-green aggregated crystals and cleavages of the extremely rare copper nitrate hydroxide, Gerhardtite. The richness of this cavity should not be understated - this is an incredibly rare species. The crystals measure a staggering 1.2 cm and look stunning with their almost unique colour and lustre.  Sparse, light to mid-blue crystal areas of Buttgenbachite occur around the edges of the cavity. A superb, large, and rare specimen from the recent find at the Likasi Mine, Katanga, Democratic Republic of Congo. Remarkable museum quality material.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780988346703,"sku":"CC17812","price":5551.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC17812_6b1e5f54-bffa-4cea-8578-0114bd4710ea.jpg?v=1783973812","url":"https:\/\/crystalclassics.co.uk\/products\/gerhardtite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
