​About This Specimen:

This exceptional polymetallic ore specimen hails from the historic Einstein Mine in the St. Francois Mountains—the only area in Missouri historically mined specifically for silver and tungsten.

​The exterior of this specimen exhibits cerussite, a heavy lead carbonate mineral that forms naturally as an oxidation and weathering product of the primary lead ores. The interior reveals fresh, highly reflective argentiferous galena (silver-bearing lead ore), which made this specific mining district famous.

​A standout feature of this piece is its light magnetic signature. The Einstein Mine is famously a tungsten-bearing locality, and this magnetism is a classic indicator of finely disseminated wolframite (an iron-manganese tungstate) in the matrix. The iron content within the wolframite creates this weak magnetic pull, adding a fascinating layer of verifiable geological history to the piece that can be demonstrated in hand.

​This is a phenomenal, dense, and historically significant piece for any serious collector of Missouri minerals or historic mining district ores.
