{"product_id":"fluorite-157","title":"FLUORITE","description":"This extraordinary large cabinet Fluorite specimen is from the less often seen location of Victory mine (Addison shaft) at Cave-in-Rock, Hardin County, Illinois.  Addison shaft is to the south of Cave-in-Rock town and adjacent to the north bank of the Ohio River.  A bed of superb purple Fluorite crystals is attached to a sandy-coloured matrix of blocky, sandy-limestone.  The Fluorite forms intergrown cubic crystals pitted with geometric, hopper-like concave structures and grade from rich blackberry-purple surfaces to pale lemon-tinged interiors.  In transmitted light the majority of the crystals are opaque with translucent faces, while towards the edges, semi-transparent crystals display nice colour zoning of blackberry and lemon-tan.  The longest cube edges measure to 4.5 cm, although the average prism size is typically 2 to 3 cm on edge.  This is an excellent Cave-in-Rock Fluorite of museum quality and size and is accompanied with its own custom-made clear acrylic base, with contour-milled recess, attached support arm and engraved label.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545152671919,"sku":"CC18671","price":5000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC18671.png?v=1770374191","url":"https:\/\/crystalclassics.com\/products\/fluorite-157","provider":"Crystal Classics","version":"1.0","type":"link"}
