Adventure Mine, Greenland, Greenland Township, Ontonagon County, Michigan, USA
On an epidote included matrix, two silver crystals show an unusual and detailed habit. The larger crystal is 1.5cm in diameter and the other is 1.3cm. What appears to be triangular etching on the spheres is actually due to twinning. Minor copper provides some contrast for the white metal. This specimen is described on pg. 234 of The John F. BarlowithMineral Collection book with a description, but was not photographed.
