The bladed crystals radiate from a common point in a starry rosette, glassy and richly coloured, sheltered inside the natural cavity of the nodule.\u003c\/p\u003e\u003cp\u003ePentagonite is a vanadium silicate and the less-common twin (dimorph) of cavansite, found in fine crystals essentially only in the Deccan Trap basalts around Pune, India. The Wagholi quarries are its main source, and this is a well-formed blue spray nested in its geode.\u003c\/p\u003e\u003cp\u003eLike the zeolites it sits among, pentagonite formed as a late secondary mineral, crystallising inside the basalt cavities from vanadium-bearing fluids long after the lava had hardened. Its blue comes from that vanadium.\u003c\/p\u003e\u003cp\u003ePentagonite is soft and fragile (Mohs around 3 to 4), so never touch the crystals. Handle the matrix only, and keep it free of dust and knocks.\u003c\/p\u003e\u003cp data-ga-exact=\"1\" style=\"margin:0 0 12px;padding:10px 14px;background:#f6f1e7;border-left:3px solid #c9a84c;border-radius:4px;font-size:0.95em;\"\u003e\u003cstrong\u003eOne of a kind.\u003c\/strong\u003e The specimen pictured is the exact piece you will receive.\u003c\/p\u003e","brand":"Gleamaura","offers":[{"title":"Default Title","offer_id":43620230987982,"sku":"25313","price":1120.0,"currency_code":"MYR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0577\/9714\/8878\/files\/1db606a2018591713812e9e3cb0f965a_8beb11c1-4728-466c-9226-2be0e261678d.jpg?v=1784696728","url":"https:\/\/gleamaura.com\/products\/pentagonite-on-matrix-4","provider":"Gleamaura","version":"1.0","type":"link"}
