{"product_id":"vanadian-dravite-tourmaline","title":"Vanadian DRAVITE Tourmaline","description":"At 7.4 cm tall, this extremely fine single crystal of Vanadian Dravite is one of the best examples of this exceptional rare and colourful variety of Dravite - a species of tourmaline better known for brown crystals. It is from the 2015\/2016 find at Nadonjukin, a small village in the northeast of Tanzania. Originally marketed as Chrome Dravite, it was not until relatively recently that the chromophore responsible for the exceptional bottle-green colour was identified to be vanadium. This substantial prismatic crystal displays an extremely well-developed three-faced pyramidal termination, with a rich gemmy bottle-green to emerald-green colour over a yellow core of Dravite. With good backlighting the intensity of colour is magnificent.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781494645071,"sku":"CC6950","price":5551.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC6950_b3c7df82-8209-4465-8358-5015fe9dcd80.jpg?v=1783991513","url":"https:\/\/crystalclassics.co.uk\/products\/vanadian-dravite-tourmaline","provider":"Crystal Classics UK","version":"1.0","type":"link"}
