{"product_id":"gratonite-3","title":"GRATONITE","description":"This well-crystallized sulphosalt thumbnail displays the extremely rare lead arsenic sulphide, Gratonite, from the area of its Type Locality - Cerro De Pasco, Peru. Described and named in 1939, the world's best crystals of Gratonite still come from Cerro De Pasco. Crystals never reach more than a few mm in length and usually coalesce as radiating aggregates, often detached from matrix as small sprays typically less than 1 cm in diameter. This small specimen displays several well-formed trigonal Gratonite crystals reaching 3 mm in length crowning a small piece of matrix mounted on an acrylic base for display. A couple of broken crystals are evident, but examples of this species are so difficult to obtain and the main crystals here are quite large.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781284405583,"sku":"CC41169","price":296.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC41169_6d92402d-c5e8-4c41-8031-3f86ac8e4f48.jpg?v=1783984837","url":"https:\/\/crystalclassics.co.uk\/products\/gratonite-3","provider":"Crystal Classics UK","version":"1.0","type":"link"}
