{"product_id":"sphalerite-with-chalcopyrite-and-quartz","title":"SPHALERITE with CHALCOPYRITE and QUARTZ","description":"A particularly interesting specimen from the well-known Greystone Quarry near Callington in Cornwall.  Sphalerite is perhaps one of the less common mineral species from this locality.  The specimen comprises a well-defined, almost metallic grey crystal measuring 2.0 cm across as part of a group of slightly less well-developed Sphalerites, resting roughly central amidst a group of terminated white to clear Quartz crystals.  A great little specimen that will compliment any collection from the locality.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780368212303,"sku":"CC10299","price":370.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC10299_70abb52a-e527-4b3e-b36a-1d25de340bac.jpg?v=1783967968","url":"https:\/\/crystalclassics.co.uk\/products\/sphalerite-with-chalcopyrite-and-quartz","provider":"Crystal Classics UK","version":"1.0","type":"link"}
