{"product_id":"sphalerite-14","title":"SPHALERITE","description":"This fine specimen of crystalised Sphalerite is obviously very old judging by the unprovenanced label glued to its base; an oval label with a magenta outer double ring and the handwritten number 56\/72.  The sphalerite is iron-rich based on its black appearance, although where crystals thin along their edges, translucent shots of reddish clove-brown appear when back-lit.  Individual crystals range from about 1 to 3 mm, but develop to form composite crystals of about, say, 1 to 2 cm wide.  The flat base reveals an inner core of micro-crystalline light grey Quartz mixed with granular Sphalerite and iron-stained orange-tan in places.  A good historic Sphalerite from Cumbria.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46584050974895,"sku":"CC14092","price":300.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC14092.png?v=1771841956","url":"https:\/\/crystalclassics.com\/products\/sphalerite-14","provider":"Crystal Classics","version":"1.0","type":"link"}
