The 6,000-square-foot Gem and Mineral Hall was opened in May of 1978 and is one of the finest permanent museum exhibitions of any kind in the Los Angeles area.
NHM's gem and mineral collection of about 150,000 specimens is the most significant in the country, west of the Smithsonian. See More

There is always something new coming to the Gem and Mineral Hall! To better discover the world of gems and minerals, we occasionally offer the public small, temporary exhibits.
