Rosasite on Smithsonite with Calcite
Silver Bill Mine, Gleason, Dragoon Mts. Cochise County
4.3 x 3.8 x 2.2 CM (miniature)
Spheres of blue Rosasite scattered on Smithsonite and some Calcite. A good locality piece that is especially fine under magnification. The Silver Bill mine has a long history but is not very well known outside of Arizona. It has been a source of Wulfenite and other species as well as Rosasite.
