- 4.1 by 3.1 by 2.1 cm – Miniature specimen (fits into a 5 cm cube)
Werner (1817) first described the mineral, but its current name came from Haidinger (1845) who named the mineral after the region of its occurrence. The mineral is a complex calcium copper arsenate carbonate (Krivovichev et al. 2006). The mineral forms 1-2 mm platy crystals, in splotchy aggregate on altered matrix. This specimen was part of the personal collection of Ralph Merrill, proprietor of the prolific mail order business Minerals Unlimited, obtained in 1956 from the Schneider collection. There is an old German label accompanying this piece. Merrill's collection card and label also ship with the specimen.
