Vanadinite crystals from the Namib Lead Mine in Namibia – miniature specimen as unique piece
This miniature specimen displays numerous finely developed Vanadinite crystals on a porous brown to ochre colored matrix. The surface is densely covered with small, clearly visible crystals that show a strong luster and create a lively sparkling texture. Small drusy cavities with tightly packed crystals are especially visible in the recesses of the matrix, giving the specimen a structured and three dimensional appearance. The crystals are clearly recognizable as individual forms and give the piece a characteristic look typical for Vanadinite from this well known locality in Namibia.
Geology & Origin
Vanadinite is a lead vanadate chloride with the chemical formula Pb₅(VO₄)₃Cl and belongs to the Apatite group. The mineral forms as a secondary mineral in the oxidation zone of lead deposits when vanadium bearing solutions react with primary lead minerals such as Galena. It typically develops short hexagonal crystals that often occur as dense crystal coatings or drusy crystal surfaces on the host rock. The Namib Lead Mine is one of the classic occurrences for this mineral in Namibia and has produced characteristic Vanadinite specimens from oxidized lead ore deposits.
