{"product_id":"willemite-var-troostite","title":"WILLEMITE var. TROOSTITE","description":"The zinc silicate Willemite forms multiple parallel stalactites of earthy deep carmine red to brownish brick red overgrown by delicate micro-acicular crystals of colourless to silvery white Willemite of the variety Troostite.  Troostite is a manganese-bearing variety of Willemite.  The earthy textured stalactites are likely a mixture of Willemite and Goethite with the longest of the group measuring 5 cm.  The rich coating of Troostite in the form of fine acicular crystals gives a play of colours in shades of silver, grey and white due to transmitted light and the underlying dark stalactites.  An unusual and fascinating miniature from Tsumeb with a M. Zinn Collection label.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46543104573615,"sku":"CC15780","price":2500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC15780.png?v=1770309695","url":"https:\/\/crystalclassics.com\/products\/willemite-var-troostite","provider":"Crystal Classics","version":"1.0","type":"link"}
