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":57780662403407,"sku":"CC12975","price":148.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC12975_0c61cdf1-8e61-4f12-9497-a666d4993b3a.jpg?v=1783969816","url":"https:\/\/crystalclassics.co.uk\/products\/quartz-pseudomorph-after-fluorite-2","provider":"Crystal Classics UK","version":"1.0","type":"link"}
