The Story of the Stone: 1.5 Billion Years of Hydrothermal Fury
Born in the violent volcanic collapse of the Precambrian St. Francois Caldera complex, this massive 2.4-pound polished slab captures the raw, chaotic power of Missouri’s deep geological history.
Superheated hydrothermal fluids surged through fractured fissure veins of quartz and topaz, depositing rich polymetallic ores. Deep-red hematite banding bleeds through the matrix, contrasting against olive-green chlorite and epidote alteration lines along ancient shear planes. Embedded within the dense, mirror-finished black jaspellite is a rich metallic ore suite: argentiferous (silver-bearing) galena, dense wolframite, and authentic arsenopyrite.
Cut with a flat base for effortless freestanding display, the front face has been brought to a brilliant lapidary finish where the glassy jaspellite and metallic sulfide veins create a striking interplay of light and texture.
Historic Provenance: The Charley Cox Collection
This piece originates directly from the historic Einstein Mine—Missouri\'s legendary 19th-century silver and tungsten deposit along the St. Francis River. It was originally acquired and preserved by Charley Cox, a distinguished alumnus of the Missouri School of Mines (MSM). Stored away and untouched in a private barn collection for decades following his passing, this specimen represents rare historic material from a now flooded collapsed dir=\"ltr\" style=\"margin-top:0; margin-bottom:0;\">Einstein Mine, Silvermines Missouri, Charley Cox Collection, Missouri School of Mines, Wolframite, Argentiferous Galena, Arsenopyrite, Silver Ore, Jaspellite, Red Jasper, Hydrothermal Vein, Zinnwaldite, Epidote, Chlorite, Topaz Quartz Vein, Madison County MO, Precambrian Geology, Ozark Minerals, Polished Slab, Lapidary Display, Freestanding Mineral Specimen, Heavy Metal Ore, Tungsten Ore, Historic Provenance, Cabinet Specimen
