The Michigan Mineralogical Society - MMS - is the premier organization in the state that seeks to educate, promote and further the science and hobby of mineral collecting, as well as an appreciation for fossils and gems. We primarily serve the southeast area of Michigan, but we have followers all over the United States and some in Canada.

Each year, the MMS hosts the largest event of professionals and hobbyists in the Midwest - the Greater Detroit Gem, Mineral and Fossil Show - which features some of the most respected dealers in the country as well as displays from world-famous museums such as the Smithsonian Institution, Royal Ontario Museum and the A.E. Seaman Mineral Museum, the official mineral museum of Michigan.

We hope you take the time to explore this website and decide to join hundreds of your fellow enthusiasts and become a member of the MMS. You'll be glad you did!
