{"product_id":"chrysocolla-ps-after-malachite-ps-after-azurite-with-quartz-9","title":"CHRYSOCOLLA ps. after MALACHITE  ps. after AZURITE  with QUARTZ","description":"This fine sculptural pseudomorph of vivid sky-blue Chrysocolla replacing Malachite after Azurite and coated in Quartz is spectacular for its large and curved and 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 partly coated with slightly coloured Quartz, hence modifying the appearance of the underlaying Chrysocolla to a vivid duck egg-blue.  Micro-crystals of dark emerald-green Malachite are scattered beneath the Quartz coating and form an 8 mm diameter rosette on one face.  The tabular Chrysocolla crystals have rounded terminations with three crystals exceeding 3 cm tall.  At least five 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 and micro-crystals.  At one side where several crystals have their sides missing, revealing internal plates of Malachite to about 2.3 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.  A beautiful and fascinating specimen of stunning colour and habit from the DR of Congo.  This specimen comes mounted on a small square, colourless acrylic base.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545289511087,"sku":"CC20870","price":1750.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC20870.png?v=1770378309","url":"https:\/\/crystalclassics.com\/products\/chrysocolla-ps-after-malachite-ps-after-azurite-with-quartz-9","provider":"Crystal Classics","version":"1.0","type":"link"}
