{"product_id":"chrysocolla-ps-after-malachite-with-quartz-and-malachite-4","title":"CHRYSOCOLLA ps. after MALACHITE with QUARTZ and MALACHITE","description":"Who doesn't love a wonderful baby blue colour? This cabinet-sized specimen from the Tenke-Fungurume area in the Kolwezi mining district, Democratic Republic of Congo (DRC) is a very striking colour, and one which is not often seen in mineral specimens. Not only is it colourful and beautiful, but is has a fine geochemical story to tell. An attractive array of pale blue bladed crystals rise up from matrix. These are blades of Chrysocolla - an amorphous copper silicate - coated with a fine layer of colourless Quartz crystals. Of course, Chrysocolla does not form crystals, let alone freestanding bladed crystals. Instead, the Chrysocolla is a pseudomorph, or replacement, of Malachite, but Malachite does not form bladed crystals like these either! So, the Malachite was also a pseudomorph, but probably after bladed Azurite, meaning that this is Quartz coating Chrysocolla pseudomorphs after Malachite pseudomorphs after Azurite. Wonderfully complex and strikingly beautiful.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781263008079,"sku":"CC36518","price":888.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC36518_6d9571e0-7d89-4de8-b71c-2b3740315e05.jpg?v=1783984516","url":"https:\/\/crystalclassics.co.uk\/products\/chrysocolla-ps-after-malachite-with-quartz-and-malachite-4","provider":"Crystal Classics UK","version":"1.0","type":"link"}
