{"product_id":"tantalite-mn-3","title":"TANTALITE-(Mn)","description":"A choice, double terminated crystal of Tantalite-(Mn) from the São João del Rei pegmatite province of Nazareno in Minas Gerais, Brazil. This ex-matrix, opaque metallic black crystal has well defined prism faces and good terminations. The surface is complexly patterned with growth structures, forming concentric stepped faces and micro-etching over the terminations. Tantalite-(Mn) forms a continuous series with Tantalite-(Fe) and was formerly named manganotantalite. It’s a very good example of Tantalite-(Mn) from this Brazilian pegmatite.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781014266191,"sku":"CC19161","price":555.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC19161_963a0e7c-149d-47d5-a473-2513b7135137.jpg?v=1783975666","url":"https:\/\/crystalclassics.co.uk\/products\/tantalite-mn-3","provider":"Crystal Classics UK","version":"1.0","type":"link"}
