Maine Mineral and Gem Museum

The Maine Mineral and Gem Museum showcases our geological history, displays renowned mineral and rock collections, provides educational opportunities for the novice and expert alike, conducts historical and geological research and is a Maine travel destination for residents and visitors. MMGM houses the finest collection of Maine minerals and gems. It includes the famous Perham Collection, viewed by generations in a local mineral store that operated for ninety years. MMGM displays one of the world’s foremost collections of extraterrestrial rocks—meteorites from Mars, the Moon and the Asteroid Belt that teach us about the origins of our Solar System. MMGM is a one-of-a-kind, world-class museum located a stone’s throw away from the Western Maine mines that once sheltered these mineral treasures.
