Structurally related to gordaite. Forms colourless hexagonal plates arranged in rosette-like aggregates.

Cu-bearing pale bluish green varieties are known from a slag locality (Herzog Julius smelter, http://www.mindat.org/loc-6026.html) in the Harz Mts, Germany (U. Kolitsch, unpublished data). They are usually erroneously labeled "namuwite".
