Superb and rare specimen of unknown pseudomorph after Fluorite, Goethite pseudomorph after Siderite, Tourmaline var. Schorl over Microcline base from Erongo Mountain, Namibia. It displays sharp pseudomorph of an unidentified mineral after Fluorite cubes with grey color. Yellow Goethite completely replaces the primary Siderite crystals with discus shape. Black prismatic Schorl crystals are seen too.  The white Microcline is sharply crystallized and it adds a nice contrast. In excellent condition. On acrylic base.
Choice and rich pseudomorph combo!
