Small milky-white Quartz crystals to 3 or 4 mm occasionally form small patches on the Tennantite.  Solid metallic Tennantite can bee seen in the specimen's base as a granular bright silver-white-grey metal.  An excellent specimen from the Tsumeb mine in Namibia.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545157390511,"sku":"CC18951","price":3500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC18951.png?v=1770374489","url":"https:\/\/crystalclassics.com\/products\/tennantite-with-quartz-1","provider":"Crystal Classics","version":"1.0","type":"link"}
