Silver/Copper - Michigan — Earth's Hidden Treasures® - Minerals, Fossils, Meteorites and Cut & Polished Stone

Earth’s Hidden Treasures® is a mineral, fossil and meteorite business that began in 1994, in Ft. Wayne, Indiana. It grew out of a passion to collect rocks, minerals and fossils - ‘hidden treasures’ - that nature has produced in an amazing array of formations, colors, shapes and sizes. When we moved to Illinois in 2002, our business came with us. We continuously seek out the most reasonably priced, quality specimens for our customers. We participate annually as vendors in several Rock and Gem shows in Georgia and Tennessee and now offer our quality specimens for sale online as we have time. We have over 100,000 specimens, most priced under $50.

Keweenaw Peninsula Copper District, Houghton County, Michigan

A "half-breed" mineral specimen features a combination of copper and silver in the same piece, a derogatory name that is used for these very uncommon specimens from upper Michigan. Having pure silver and pure copper occur in the same specimen is very rare. This one having rounded crystal faces rather than just a rounded nugget gives it even more character.
