The smallest part of the Zuhl Geological Collection, but nonetheless of great quality, are minerals and rocks from throughout the world.

Particularly impressive are specimens of rhodochrosite, malachite, and rutilized quartz.  Many of the rocks were ground and polished into spheres ranging in size from a few centimeters to a meter in diameter.
