Chrysocolla ps. after Malachite ps. after Azurite with Quartz

A spear-shaped double pseudomorph of intense sky-blue Chrysocolla replacing Malachite after Azurite and coated in Quartz, from a magnificent recent find in the Tenke-Fungurume area of the Democratic Republic of the Congo (DRC) in Central Africa.  This former tabular Azurite crystal, now pseudomorphed to Chrysocolla, forms a tapering curved flattened habit and is entirely encrusted with sparkling micro-Quartz crystals with a bright glassy lustre.  The Quartz is particularly rich on this specimen, so giving a lustrous rough sucrosic granular surface texture.  The Chrysocolla is a stunning sky-blue and throughout the base (as observed through its acrylic base) can be seen a remnant core of emerald-green Malachite.  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 choice Quartz-coated Chrysocolla pseudomorph from the Kolwezi mining district of the DRC.  This specimen comes mounted on a small square, colourless acrylic base.
