Rhodochrosite, calcite,sphalerite,galena, quartz

The small beauty. One very aesthetic thumbnail specimen of flat calcite „paper spat“ crystals developed on the top of galena , sphalerite and quartz. In the end very nice ball like, rounded with  pale pink color rhodochrosite  crystals were developed.
