{"product_id":"quartz-pseudomorph-after-fluorite-2","title":"QUARTZ pseudomorph after FLUORITE","description":"A roughly triangular thin plate of orange-tan Chalcedony has its top surface covered with opaque milky Quartz pseudomorphs after octagonal Fluorite crystals, a classic specimen from Wheal Mary Ann at Menheniot in Cornwall.  Characteristic of this locality, the pseudomorphs form the upper four-sided pyramidal faces of each octahedron and measure between 3 and 8 mm across, with part-octahedrons of up to 1.5 cm on edge.  A great example of this classic Wheal Mary Ann pseudomorph.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46584044388527,"sku":"CC12975","price":200.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC12975.png?v=1771841204","url":"https:\/\/crystalclassics.com\/products\/quartz-pseudomorph-after-fluorite-2","provider":"Crystal Classics","version":"1.0","type":"link"}
