Superb and rare specimen of goethite pseudomorph after siderite decorating tourmaline var. schorl from Erongo Mountain, Namibia. It displays a yellow goethite completely replacing the primary siderite crystals with a discus shape. Black schorl crystal forms the base. It is sharp and well formed.  The contrast is strong. It displays attractively all over 360 degree.  In excellent condition. On acrylic base.
Choice pseudomorph combo!
