{"product_id":"apophyllite-with-stilbite-and-heulandite-b-natural-india","title":"Apophyllite with stilbite and heulandite (B) — natural, India","description":"\u003cp class=\"p1\"\u003e\u003cmeta charset=\"utf-8\"\u003eA natural association of apophyllite, stilbite, and red heulandite from the basalt of the Deccan Traps, Maharashtra, India. Each mineral here tells you it belongs to this place: the stilbite in soft sheaf-like or bowtie clusters, the tabular heulandite warmed to red-orange by natural iron, and the apophyllite in bright, blocky crystals. Apophyllite is not a zeolite itself, but it almost always forms alongside them in the same volcanic cavities, which is why the three so often appear together on one piece.\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\u003e6 × 4.3 × 4.3 cm\u003cb\u003e\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e \u003c\/b\u003e124 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":57954082619736,"sku":null,"price":24.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/4880\/5720\/files\/58300B8E-59D1-4126-897D-742F308444B3_1_105_c.jpg?v=1786616892","url":"https:\/\/thecrystalshowroom.com\/products\/apophyllite-with-stilbite-and-heulandite-b-natural-india","provider":"The Crystal Showroom","version":"1.0","type":"link"}
