Mineralogical Society


The Morris Museum Mineralogical Society (MMMS) was founded in 1971 to promote interest and education in the various earth sciences and, in particular, the subjects of geology, mineralogy, paleontology, lapidary and related subjects.

The MMMS meets monthly*, except July and August. Most meetings feature a speaker who delivers an illustrated lecture.

The society also hosts Rock and Mineral Weekend on Thanksgiving weekend every year at the Museum. After many years of hosting the Gem, Mineral, and Fossil sale on the grounds of Delbarton School in Morristown, the show is now held in August on Museum grounds.

For more information about membership in the club and its activities, email [email protected]

*virtual meetings usually start at 7:15 p.m. on the third Thursday of the month. In person meetings may be held on select Saturdays at Morris Museum.  All meeting days and times are subject to change. Please contact [email protected] for current schedule.
