{"product_id":"mottramite-3","title":"MOTTRAMITE","description":"Mottramite is a lead vanadate hydroxide and at the Tsumeb mine in Namibia occurs in a bewildering variety of habits and colours.  Mottramite is typically some shade of green at Tsumeb and although this specimen is, it so dark a shade of green it appears jet black.  This large miniature or small cabinet specimen forms as a gently curved plate of stacked Mottramite crystals with an appearance more of Descloizite.  These two species do form a continuous solid solution series, the Descloizite-Mottramite Series, ranging from the pure lead-zinc Descloizite end member to lead-copper Mottramite.  Possibly this specimen lies within this series a little from the pure Mottramite end.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545157030063,"sku":"CC18895","price":500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC18895.png?v=1770374446","url":"https:\/\/crystalclassics.com\/products\/mottramite-3","provider":"Crystal Classics","version":"1.0","type":"link"}
