A rich specimen covered with colorful blue microcrystals of this extremely rare Cadmian Copper Sulfate species named after Gerhard Niedermayr (b. 1941), mineralogist and geologist, Naturhistorisches Museum, Vienna, Austria. While not from the same mine as the type material, this is from a recent find which was available at the Munich 2010 show, from a nearby mine in the same ancient district.
