{"product_id":"sphalerite-with-quartz-and-dolomite","title":"SPHALERITE with QUARTZ  and DOLOMITE","description":"Excellent individual, complex and lustrous black Sphalerite crystals to 1.5 cm are scattered over an elongated mound of milky Quartz and Dolomite crystals.  The Quartz has a bright glassy lustre and the glossy, cream saddle-shaped Dolomite crystals cover an altered limestone matrix.  Patchy overgrowths of more earthy, orange-tan Dolomite crystals give additional contrast to this high-quality specimen of the more common minerals from the Alston Moor mining district of east Cumbria, in northern England.  This cabinet specimen is accompanied with a previous German collector's label and an ex. Department of Mineralogy, British Museum (Natural History) label (BM36006), obtained by the museum in 1864.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46542957478063,"sku":"CC10313","price":1500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC10313.png?v=1770296177","url":"https:\/\/crystalclassics.com\/products\/sphalerite-with-quartz-and-dolomite","provider":"Crystal Classics","version":"1.0","type":"link"}
