[Fire opal] The mineral cabinet displays 300 specimens of essential minerals. They belong to the mineral collection of the Department of Mineralogy/Petrography founded in 1986 at Bremen University. 
[Agate] The minerals are split up into 8 classes according to the internationally recognized STRUNZ Mineralogical Tables. The systematic classification is based on a combination of chemical and crystallographic criteria and thus provides strict and consistent classification. 
[Lasurite] The structural formula, a short description (occasionally with an alternate mineral name) and the locality are stated for every mineral. [Amazonite] Comments about the provenance of the minerals describe the circumstances at the time of the mineral discovery and hence do not in all cases reflect current political boundaries.
