Gems and Minerals Hall Renovation
A Classic Hall: Reimagined
The Denver Museum of Nature & Science is embarking on one of the most ambitious renovations of a permanent exhibition in its history—an extraordinary effort to expand and reimagine its classic Gems and Minerals Hall.
Slated to begin in 2026, this transformative project will expand the hall by 50%, creating an immersive, multi-sensory experience inspired by our community’s desire to feel transported into an underground world. Visitors will explore minerals in their natural forms and uncover the essential role they play in our everyday lives through the big idea: “My World is Made of Minerals.”
This new, awe-inspiring experience will fuse the latest in groundbreaking exhibition design with a bold new approach to telling the story of Earth’s most precious stones and resources. Venturing into mysterious underground environments, visitors will marvel at the wonders of geological discovery and contemplate the rich and complex relationship between humans and the minerals that make up our world.
Originally opened to the public in 1982, the Coors Hall of Gems and Minerals remains one of the Museum’s top three most-loved permanent exhibitions. This renovation is a rare opportunity to honor that legacy while igniting a fresh spark of wonder, learning, and connection for generations to come. The new Dea Family Gems & Minerals Hall is planned to reopen in 2027.
Celebrating the Past and Shaping the Future: Gems & Minerals at the Museum

Over the decades, the Museum has continually evolved, enhancing the visitor experience and reimagining how Earth’s natural treasures are shared with the public.
