Welcome to MMS

From the MMS Board of Directors,


For everyone's safety, we have temporarily suspended group activities until our state and local leaders have determined we are able to safely gather again. In no way does this mean that the club is closed. We have merely stopped meeting in groups. We will still provide updates and newsletters as best we can for the time being. Please contact us if you have any questions, especially for anyone who has recently joined.

Be safe and think of other's safety at this critical time.

For the Kid in All of Us!

We added in a new Young Collectors Resources Page for the less seasoned "Miners". You can find it under our Links and Resources tab.


Featured MIneral


Pyrolucite - from the Greek, pyro and louein, “fire” and “to wash,” because it was used to remove the greenish color imparted to glass by iron compounds. Pyrolusite is a mineral consisting essentially of manganese dioxide (MnO2) and is important as an ore of manganese.

Mineral of the Month


For our "Mineral of the Month" we'll tell you about the newly discovered mineral Petrovite. It was found in Kamchatka, and may be a low cost inspiration to replace lithium batteries.

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!
