Collection: Minerals
The Mineralogical Museum's mineral collection contains minerals, gemstones and precious stones as well as syntheses and imitations of minerals. The collection provides the basis for mineralogical research and teaching at the University of Hamburg. It has grown since 1988 from about 1,600 to date (2022) about 3,155 of the currently approximately 5,800 recognized mineral species, making it one of the largest mineralogical reference collections in Germany. In the context of geodiversity research, numerous new minerals have been scientifically described in the Mineralogical Museum and are deposited in the museum as so-called type minerals.
