Native Silver Crystal Cluster – Wolverine Mine, Houghton County, Michigan
Ex-Thomas M. Kohnen Collection
An unusual native silver specimen from the historic Wolverine Mine in Calumet Township, Houghton County, Michigan, featuring an intricate cluster of naturally formed metallic silver.
This attractive miniature displays several thick, branching projections extending outward from a central mass, creating a distinctive three-dimensional formation.
The specimen exhibits a combination of warm bronze-gold metallic tones and darker gray to black areas of natural surface tarnish. Portions of the silver display reflective metallic surfaces, while other areas feature intricate textures, irregular growth patterns, and naturally sculpted contours.
The branching formation gives the specimen a particularly interesting appearance, with multiple prominent projections visible from different viewing angles.
The Wolverine Mine is part of Michigan’s historic Keweenaw Peninsula copper mining district, an internationally recognized region famous for its native copper and associated metallic mineral occurrences.
Native silver specimens from Michigan’s copper district are particularly interesting to collectors of native elements, historic American mining localities, and metallic mineral specimens.
This example offers an unusual sculptural appearance, attractive metallic coloration, and documented collection provenance.
