Rocks, Minerals, Gems, and Micromounts

Our collections are anchored by diverse minerals from historic mining districts, regionally relevant building stones, K-Pg boundary strata from around the world, Colorado gold, and one of the largest museum collections of diamonds. Many of our most iconic specimens are on display in Coors Hall of Gems & Minerals.
