{"product_id":"spinel","title":"SPINEL","description":"Franklin mine in New Jersey needs no introduction and this fabulous Spinel crystal will make a great addition to any collection centred on this most famous locality. The Spinel forms a perfect octahedral crystal, its lower four faces remaining embedded in the white Calcite matrix. Its upper pyramidal edges measure 1.8 cm and are all razor-sharp. Two faces are mirror-smooth while two display a rougher texture, mainly due to interruptions produced by growth patterns. The crystal appears jet-black and at first could be mistaken for Franklinite, but close inspection reveals it to be intensely dark inky blue. A fine and quite rare example of well crystallized Spinel from the Franklin mining district in Sussex County, New Jersey, USA.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781147828559,"sku":"CC21842","price":1110.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC21842_a38dd502-9b6d-48b8-8761-359b249ff175.jpg?v=1783979689","url":"https:\/\/crystalclassics.co.uk\/products\/spinel","provider":"Crystal Classics UK","version":"1.0","type":"link"}
