Pockets like the one this grew in are found when quarrying or well-digging breaks into gas cavities left in the basalt, revealing crystals that formed slowly inside. The apophyllite stands out in clear, blocky crystals, set against the softer stilbite and the iron-reddened heulandite.\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cb\u003e\u003cstrong\u003eMineral:\u003c\/strong\u003e \u003c\/b\u003eApophyllite (KCa₄(Si₈O₂₀)(F,OH)·8H₂O), stilbite and heulandite (zeolite group aluminosilicates)\u003cb\u003e\u003cbr\u003e\u003cstrong\u003eCrystal system:\u003c\/strong\u003e \u003c\/b\u003eApophyllite tetragonal; stilbite and heulandite monoclinic\u003cb\u003e\u003cbr\u003e\u003cstrong\u003eOrigin:\u003c\/strong\u003e \u003c\/b\u003eDeccan Traps, Maharashtra, India\u003cb\u003e\u003cbr\u003e\u003cstrong\u003eHardness:\u003c\/strong\u003e \u003c\/b\u003e4.5 to 5 for apophyllite, 3 to 4 for the zeolites; a soft, delicate specimen, handle by the base\u003cb\u003e\u003cbr\u003e\u003cstrong\u003eTreatment:\u003c\/strong\u003e \u003c\/b\u003eNone\u003cb\u003e\u003cbr\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e \u003c\/b\u003e9.3 × 7.17 × 4.76 cm\u003cb\u003e\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e \u003c\/b\u003e367 g\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eYou'll receive the exact piece photographed.\u003c\/p\u003e","brand":"The Crystal Showroom","offers":[{"title":"Default Title","offer_id":57954491171160,"sku":null,"price":59.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/4880\/5720\/files\/asrh-c-5.jpg?v=1786619039","url":"https:\/\/thecrystalshowroom.com\/products\/apophyllite-with-stilbite-and-heulandite-c-natural-india","provider":"The Crystal Showroom","version":"1.0","type":"link"}
