Native Silver & Native Copper Michigan, USA "Some fans of silver crystals up to about 1.25 inches growing on native copper. The specimen is about 4.5 inches across. I got this specimen when I sold Earl Calvert's collection for the family many years after he died. The specimen had a lot of quartz growing on and amongst the silver crystals. I removed it with Hydrofluoric acid. It remains on of the best of its kind from any locality." - Rock H. Currier This is just another fabulous combination of Native Silver and Native Copper from Michigan, with massive amounts of esthetics heaped on. Any number of institutions, or collectors, would kill for this. There is a custom labeled base. Overall Measurements: 4.7 x 2.8 x 2.0 inches (12.0 x 7.0 x 5.0 cm) Provenance: Ex. Earl Calvert Collection [RHC #6849, acquired 2000] [Scale: 1 inch, with mark at 1 cm]
