RARE 193g Silver Mines MO Ore - Bladed Wolframite Crystal, Silver Galena & Topaz For Sale

A Dense, Brecciated Koch Shaft Powerhouse

This Beautiful beast is a remarkably heavy, 193-gram multi-mineral ore specimen sourced from the historic Koch Shaft at the legendary Einstein Mine (Silver Mines) in Madison County, Missouri. Small in size but packing incredible density, this piece represents a violently fractured and recemented hydrothermal greisen vein loaded with rare mineralization.

​Mineralogical Highlights

• ​Bladed Wolframite Crystal: The centerpiece of the main display face is a distinct, sharp, dark prismatic blade of Wolframite (Ferberite) embedded directly into the matrix.

• ​Crystalline Topaz Crest: The upper crown of the specimen features a sparkling cluster of gemmy Topaz and hydrothermal Quartz, coated in brilliant fiery-gold and amber iron-oxide staining.

• ​Argentiferous Galena: Nestled into the crystalline pockets and laced through the vein are lustrous, metallic silver-bearing Galena cleavage faces.

• ​Zinnwaldite Greisen Matrix: The host rock is a classic hydrothermal breccia composed of sparkling golden-olive Zinnwaldite mica flakes and a network of dark submetallic tungsten stringers.

This piece comes directly from the historic Cox Collection, representing authentic old-stock Missouri mining heritage from one of the most famous localities in the Midwest.
