{"product_id":"cuprian-smithsonite-23","title":"CUPRIAN SMITHSONITE","description":"This really unusual Tsumeb mine Smithsonite is not only a lovely peppermint green colour, but has an intriguing form too. It is a thin cast after an unknown mineral and the Smithsonite is not only copper-rich, or cuprian, but has occasional tiny pale emerald green Dioptase inclusions. Its overall shape I liken to a slug. Several old collection labels accompany the specimen, one of which notes that it is ex Ed David and possibily ex Smithsonian. It is a very strange Smithsonite, whose form is most similar to the famous Dolomite casts seen from Tsumeb, so perhaps the carbonate geochemistry shifted from magnesium and iron to zinc-rich.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46543106441391,"sku":"CC15853","price":2000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC15853.png?v=1770309761","url":"https:\/\/crystalclassics.com\/products\/cuprian-smithsonite-23","provider":"Crystal Classics","version":"1.0","type":"link"}
