About our club

The Michigan Gem and Mineral Society (MGMS) is a chartered non-Profit 501c3 organization, which held its first meeting on March 4, 1954. It is a gathering of like-minded rock, mineral and fossil enthusiasts who come together to share their common interest and make new friends and share their stories.

During the year MGMS goes on several field trips to different locations in Michigan, Ohio and Indiana. These are different opportunities to have fellowship and collect new specimens of rocks, minerals and fossils to add to your collection – or to begin a new collection! These field trips are announced in the newsletter, via email or at this site.

See the General Member Info page for more details about MGMS and how to join. New members are always welcome!


If you wish to join MGMS, there is a modest yearly fee of only $15.00 per adult (17 years and older) or $20.00 per family. A family is considered to be all members living under the same roof. What a bargain! Yearly membership fees are payable – and due – on March 25th of each year.
