The Michigan Mineralogical Society was organized in 1935 by a Michigan group of mineral collectors interested in furthering the hobby of mineral, fossils, gem collecting, geology, and earth science education in Michigan.

The Society is incorporated as a non-profit educational organization and is a member of both the American Mineralogical Societies and Midwest Federation of Mineralogical and Geological Societies.

Organized in March 1935, it is the oldest Society/Club in the Midwest Federation and in Mid America. “The Conglomerate” is the official bulletin of Michigan Mineralogical Society, first published in 1940 and is one of the oldest in the United States.

Today, membership is open to all persons interested in the education and promoting interest in all aspects of collecting, mineralogy, paleontology, and the earth sciences.

The Michigan Mineralogical Society meets on the second Monday of the month, September through May (except October and January) at the prestigious Cranbrook Institute of Science, 39221 N. Woodward Ave. Bloomfield Hills, MI 48303.

At the meetings, doors of the Institute open at 7:00 p.m. to allow time for MMS members and their guests to enjoy the mineral hall exhibits. Programs begin at 7:30 p.m. Visitors are always welcome at meetings.

Membership applications may be obtained on this site or at the meetings. Annual Dues: Adult $20.00 Students $5.00, New member initiation fee of $5.00 with annual dues.
