Allison and Roberto Mignone Halls of Gems and Minerals

The Mignone Halls of Gems and Minerals tell the fascinating story of how the vast diversity of mineral species arose on our planet, how scientists classify and study them, and how we use them for personal adornment, tools, and technology. The galleries feature more than 5,000 specimens from 98 countries. 

These halls are included with any admission.
