{"product_id":"cronstedtite-1","title":"CRONSTEDTITE","description":"A well-formed partial radial cluster (covering 100 degrees of a circle) of lustrous black acicular Cronstedtite crystals measuring to 9 mm in length is nestled in a cavity lined with crystallized Quartz, dark brown Siderite and yellowish Goethite. This crystal spray presents very well and is a fine example of Cronstedtite crystals. Several smaller vugs also contain good and sizable Cronstedtite crystals, all in a characteristic Quartz veinstone for Wheal Jane mine at Baldhu, Kea, in Cornwall, England. This mine was a little to the west of Cornwall’s cathedral city and county town, Truro. Areas of very dark green Chlorite; metallic golden Pyrite and Chalcopyrite and reddish granular Siderite are also in present. Cronstedtite, an iron silicate, is a mineral particularly associated with Wheal Jane and this is a particularly good display example, small cabinet in size.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780839383375,"sku":"CC13323","price":1110.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC13323_273a523c-d142-46c6-a8a1-fa4a7e16f250.jpg?v=1783970142","url":"https:\/\/crystalclassics.co.uk\/products\/cronstedtite-1","provider":"Crystal Classics UK","version":"1.0","type":"link"}
