Mineralogical museum of the University of Bonn

The exhibition with international status covers four rooms, focussing on four subjects - minerals and their classification, rocks and meteorites, ores and mineral raw materials, precious stones - over an area covering about 500 square metres.
The centre point is the classification of the approximate 550 most important minerals. The rooms with rocks and meteorites presents minerals that form small, irregular crystal compounds, which can grow together into rocks. In the Lagerstättensaal the various sources of usable minerals and how they were formed are demonstrated. The Edelsteinsaal containing precious stones is the museum's jewellery box. Here you can see minerals used to make jewellery as raw, unpolished stones.
