New downtown gem museum nears completion

Tucson’s new 12,000-square-foot gem and mineral museum, with exhibitions design by Ralph Appelbaum Associates, is expected to be completely finished within the next month; the museum features more than 2,200 specimens from collections held by the University of Arizona and its loan partners, and is one of the latest new attractions waiting to make its post-pandemic debut at the historic courthouse.
