{"product_id":"chrysocolla-ps-after-malachite-ps-after-azurite-with-quartz-1","title":"CHRYSOCOLLA ps. after MALACHITE ps. after AZURITE  with QUARTZ","description":"This museum-grade double pseudomorph of vivid sky-blue Chrysocolla replacing Malachite after Azurite and coated in Quartz is spectacular for its large and perfect curved tapering crystals and a cross-sectional glimpse into the internal structure and paragenesis of the replacement process.  This specimen is from a magnificent recent find in the Tenke-Fungurume area of the Democratic Republic of the Congo (DRC) in Central Africa.  From one direction the Chrysocolla is a stunning sky-blue, so vivid and intense it verges on turquoise.  This colour is intensified by a pervasive coating of sparkling micro-Quartz crystals with a bright glassy lustre.  The opposite side of the specimen has been coated in parts with a slightly coloured Quartz, so dulling the appearance of the underlaying Chrysocolla.  The tabular Chrysocolla crystals taper towards their Gothic window-like terminations with the central crystal attaining 5 cm.  At least eight individual crystals can be identified amongst this group.  Adding great interest are remnant cores of mid and deep leaf-green Malachite occurring as both earthy slivers and micro-crystals.  At one side where several crystals have their sides missing, this reveals internal plates of Malachite to about 2.6 cm tall.  The Tenke-Fungurume area delineates a 30 km copper-cobalt mineralised zone between Tenke hill in the NW and Fungurume hill in the SE of the Kolwezi mining district.  The region holds large ore reserves and to date a suite of 31 minerals have been recorded, including some exceedingly rare copper species.  This is a world-class specimen of amazing colour and habit and will grace the best of collections.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545289248943,"sku":"CC20840","price":7500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC20840.png?v=1770378282","url":"https:\/\/crystalclassics.com\/products\/chrysocolla-ps-after-malachite-ps-after-azurite-with-quartz-1","provider":"Crystal Classics","version":"1.0","type":"link"}
