{"product_id":"calcite-on-sphalerite-1","title":"CALCITE   on SPHALERITE","description":"Calcite is one of the world's commonest mineral species and yet it is remarkable that specimens from one mine can be so instantly recognizable - that being Elmwood mine, Carthage, Smith County, Tennessee, USA. This cabinet specimen displays a characteristic gemmy, orange tipped, glassy, doubly-terminated scalenohedral Calcite crystal or, more correctly, a 'macle twin' sat upon large, glossy black Sphalerite crystals. The Calcite crystal looks stunning, with sharp, well-defined faces, excellent colour and brightness, and in such a perfect, prominent position for display. It is at least 6 cm in length and is in great condition: there appears to be a small cleaved section on the back of the upper crystal tip, but this is not seen from the display angle. Otherwise, it is absolute perfection and simply glows.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781309931855,"sku":"CC42800","price":2591.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC42800_a09960eb-669b-4b61-9aa8-922a3808b5de.jpg?v=1783985648","url":"https:\/\/crystalclassics.co.uk\/products\/calcite-on-sphalerite-1","provider":"Crystal Classics UK","version":"1.0","type":"link"}
