Plumbogummite Group Locality: Silver Coin Mine, Valmy, Iron Point District, Humboldt Co., Nevada, USA The picture shows two minerals both belonging to the plumbogummite group. The rosettes of small tabular crystals, white, may be referred to the perhamite. Above these, other rosettes of tabular crystals, hexagonal, larger than the previous, with the base pearly white and with the “prismatic”, pink meat. Collection and photo of Gianfranco Ciccolini.
