{"product_id":"fluorite-polished-octahedral","title":"Fluorite (Polished Octahedral)","description":"\u003cp data-start=\"90\" data-end=\"452\"\u003eThis fluorite formed within hydrothermal veins that developed as mineral-rich fluids moved through the limestone formations of southern Illinois. Over time, changing temperatures and chemistry allowed fluorite crystals to slowly grow within open spaces, producing the vivid color zoning and clarity for which the Cave-in-Rock District is internationally known.\u003c\/p\u003e\n\u003cp data-start=\"454\" data-end=\"824\"\u003eThe rich purples, blues, and golden tones seen in fluorite from this region are caused by trace elements and natural radiation exposure during formation. While fluorite most commonly develops as cubic crystals in nature, this specimen has been carefully polished into an octahedral form that emphasizes the mineral’s natural cleavage directions and internal structure.\u003c\/p\u003e\n\u003cp data-start=\"826\" data-end=\"1145\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eThe Cave-in-Rock District has long been regarded as one of America’s classic fluorite localities, producing some of the finest material in the United States. Geometric, luminous, and deeply colored, this piece highlights both the natural beauty of fluorite and the remarkable geology of the Illinois fluorspar region.\u003c\/p\u003e","brand":"Mineral Nexus","offers":[{"title":"Default Title","offer_id":43376544841818,"sku":null,"price":60.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/2504\/6618\/files\/MN0364-FluoritePolishedOctahedral-Illinois-_60_15_-Edited.jpg?v=1778786988","url":"https:\/\/themineralnexus.com\/products\/fluorite-polished-octahedral","provider":"Mineral Nexus","version":"1.0","type":"link"}
