Formula:
Cu3(AsO4)2 · 8H2O
Generally contains Co, Zn, Mg or other, apparently stabilising, divalent cations replacing Cu.
Colour:
Pinkish to peach-colored
Lustre:
Vitreous
Hardness:
1½ - 2

Name:
Named in honor of František Babánek (born October 10, 1836, in Kamenný Přívoz near Jílové, Bohemia; died February 25, 1910, in Prague), Czech mining expert, geologist and mineralogist. Babánek worked in Příbram and later in Jáchymov, the two most important mining districts in Bohemia, then a part of the Austro-Hungarian Empire.
Easily confused with erythrite and other pink solid-solution members of the vivianite group.
