Short summary
The article provides the standard description of bonacinaite, Sc3+(AsO4)·2H2O, the first natural scandium arsenate. The new mineral species was found in a few specimens in the dumps of the old Varenche Mine, Valle d'Aosta, Italy, which is therefore the type locality and the only locality in the world. Bonacinaite forms colourless (with faint to distinct violet tints), pseudohexagonal, thick tabular crystals, up to 0.25 mm in size, or as small, faintly violet lath-shaped crystals.
