{"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":46542957346991,"sku":"CC10299","price":500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC10299.png?v=1770296162","url":"https:\/\/crystalclassics.com\/products\/sphalerite-with-chalcopyrite-and-quartz","provider":"Crystal Classics","version":"1.0","type":"link"}
