{"product_id":"fluorite-with-marcasite","title":"FLUORITE with MARCASITE","description":"Less seen nowadays, this superb cabinet-sized matrix-less aggregate of large (to 6 cm on edge) intergrown stepped cubic crystals of translucent to transparent Fluorite comes from the Chaillac mine, at Indre, Centre-Val de Loire, France. Most specimens like this were mined during the mid-1990s and are renowned for their superb appearance under backlighting, which brings out their wonderful honey-coloured core. The outer surface of the crystals is pale lilac-grey and studded with small golden to brassy tetragonal crystals that appear to be Chalcopyrite alongside tiny golden crystals of Marcasite, most of which are inclusions within the outer parts of the Fluorite crystals. In overall excellent condition, with sharp, intact crystal edges and corners, this also displays extremely well. Ex Reverend Michael Keirle Collection (Jersey).","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":50549164179631,"sku":"CC64521","price":1400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC64521_Fluorite_with_Marcasite_Chaillac_mine_France_IMG_4430ed.jpg?v=1790677508","url":"https:\/\/crystalclassics.com\/products\/fluorite-with-marcasite","provider":"Crystal Classics","version":"1.0","type":"link"}
