Maine Mineral & Gem Museum
Exceptional local minerals, gemstones, mining history, and extraterrestrial material move from the state’s pegmatites to planetary science.

Artwork inspired by Bernard Langlais
Maine geology meets meteorites and the origin of the solar system. Exceptional local minerals, gemstones, mining history, and extraterrestrial material move from the state’s pegmatites to planetary science. Specimens are displayed for both beauty and geological explanation. A slower reading reveals how mining history supplies context for meteorite collection, giving the headline subject a clearer local scale and consequence.
Begin with Maine minerals, learn one formation process, then test that knowledge in the meteorite galleries. Special programs and laboratory experiences have separate schedules; allow more time than the compact exterior suggests. At Maine Mineral & Gem Museum, the most rewarding visit connects objects, spaces, and interpretation instead of treating the institution as a checklist.

- Look closely at
- Compare meteorite collection with mining history; the relationship reveals something the headline feature alone cannot.
- Connect the story
- Trace local pegmatite minerals into mining history, then use the meteorites to widen that geological timeline beyond Earth.
- Plan around
- Check the official calendar before leaving, then protect time for mining history after Maine pegmatites establishes the main story.
