{"product_id":"mottramite-4","title":"MOTTRAMITE","description":"Mottramite was the first species I ever encountered from Tsumeb and so remains one of my favourite minerals from this world-famous mine. This small miniature is interesting alone for its high density, a property readily appreciated as soon as it is handled. The specimen is composed entirely of Mottramite, an anhydrous vanadate hydroxide forming coliform mounds and fronds, rising vertically from a flat base. Characteristic of certain habits of Mottramite at Tsumeb, undulating folds ripple across the mounds, delineating individual Mottramite crystals. The overall colour is of darkish forest green with a rusty speckled dusting, and from the opposite direction, a preferential layer of much brighter, limey-pistachio green highlights this delightful specimen. I should add that the Tsumeb mine is in Namibia, but suspect everyone reading this already knows!","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781239710031,"sku":"CC32539","price":703.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC32539_095a726c-4f59-487c-8e04-6fa814a294bb.jpg?v=1783983918","url":"https:\/\/crystalclassics.co.uk\/products\/mottramite-4","provider":"Crystal Classics UK","version":"1.0","type":"link"}
