An exceptionally beautiful example of a heřmanovská sphere with a preserved complete core and cap. The so-called core of the sphere (flat pit/lens) is composed of dark shiny phlogopite, which is rimmed all around by radially arranged needles of silver-gray anthophyllite. The outer edge of the sphere is again covered with a thin layer of phlogopite scales. This is a very rare mineralogical curiosity.
