crystal system
In crystallography, a crystal system is a set of point groups (a group of geometric symmetries with at least one fixed point). A lattice system is a set of Bravais lattices (an infinite array of discrete points). Space groups (symmetry groups ...

History
Its occurrence was first confirmed in the
Sieroszowice copper mine, Lubin-Sieroszowice district, Poland.
Etymology
The mineral is named in honor of Eugen Friedrich Stumpfl (27 November 1931, Munich, Germany - 12 July 2004, Innsbruck, Austria), professor of mineralogy, Mining Institute, Leoben (Austria), for his studies of noble metal compounds.
Physical properties
It has a silver white color. And it is metallic and isometric.
Occurrence
It is mostly found in cuprite and in low-grade copper sulfide ores in shale and carbonate rocks.
