Polianite (Pyrolusite pseudo after Manganite) (Ref: AX-10-869)

Alberta, Baraga County, Michigan, United States
80mm x 55mm x 31mm
minID: RQN-APN
$160
A choice Michigan specimen with sharp black-silvery crystals that are a perfect replacement of Manganite. Most likely from the Taylor mine but there is no documentation of that detail. From the Palmer collection that was assembled in conjunction with the late Dr. Joe Mandarino for use in his research and publications. The crystals are quite sharp and lustrous reaching to 1 CM some are also free standing.
