Beryl var. Aquamarine and Goethite ps Calcite, Erongo Mountains, Erongo Region, Namibia
8.4 x 6.3 x 3.4 cm.
This is an incredible rarity from the Erongo Mountains. Seen these disk shaped goethite pseudomorphs associated with quartz and small schorl crystals but never with an aquamarine crystal. There can't be more that just a handful of these specimens in existence. The aqua is fully terminated and has a nice deep blue color. No damage.
