LCT pegmatites are rich in Lithium, Caesium, and Tantalum, but do contain various other rare elements; the element necessary to form many of the gem minerals this wonderful mine contained, and still contains!","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780936966479,"sku":"CC14515","price":1332.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC14515_a2712181-72b0-4587-b605-f142602a2851.jpg?v=1783970892","url":"https:\/\/crystalclassics.co.uk\/products\/tourmaline-20","provider":"Crystal Classics UK","version":"1.0","type":"link"}
