Regional guide
Topaz from Erongo Mountains, Namibia
The Erongo Mountains produce one of the more distinctive African topaz styles: pale blue, pale green, or colorless crystals from miarolitic cavities in a granite-dominated volcanic complex, often accompanied by schorl, feldspar, smoky quartz, fluorite, aquamarine, muscovite, or goethite. Unlike the more familiar Namibian topaz from the Spitzkoppe area, Erongo topaz is valued less as loose gem rough and more as a specimen mineral—etched, glassy, sharply terminated, and best of all still attached to its original pocket matrix.
