Wulfenite crystals from the Tsumeb Mine, Otavi Mountains, Namibia – Min as unique piece
This miniature specimen displays densely arranged Wulfenite crystals from the legendary Tsumeb Mine in the Otavi Mountains, Namibia. The crystals are predominantly tabular to sharply defined and show warm reddish-brown to honey-colored tones with a strong metallic to vitreous luster. The close intergrowth of the crystals creates a compact, richly structured surface, giving the specimen a powerful yet well-balanced visual appearance. The clear crystal development and intense coloration make this a highly characteristic and collectible example of Wulfenite from Tsumeb.
Geology & origin
Wulfenite is a secondary lead molybdate that forms in the oxidation zones of lead-bearing deposits. The Tsumeb Mine in the Otavi Mountains is regarded worldwide as one of the most important localities for exceptionally well-developed Wulfenite crystals. The extraordinary chemical diversity of the deposit favored the formation of numerous high-quality secondary minerals. This specimen represents the classic paragenesis and the outstanding standard for which Tsumeb is internationally renowned.
