Museum of Mineralogy / Collection of Gems from Romania

The Collection of Gems from Romania includes 3,500 fine stones, of which over 1,200 are displayed on theme panels (from regional and compositional points of view). It was founded in 1987, based on the material collected throughout the decades of activity by the members of the Mineralogy Department of the Babeş-Bolyai University. It consists of minerals and rocks from over 90 occurrences in the country, which can be used for manufacturing jewelry or decoration objects. The varieties of quartz and opal dominate, but other minerals or even common rocks are also present, these being used more rarely for gemological purposes.

In addition to these, there is the collection "Ornamental Gems and Rocks from Transylvania presented at the World Exhibition, Paris 1900", consisting of 35 polished fragments of chalkstones and marbles, polished plaques and fragments of calcite with aragonitic aspect, and aragonite from Corund, Harghita county, as well as diverse types of chalcedony and opal (39 polished samples).
