DMS is a non-profit organization dedicated to the promotion and education of mineralogy, paleontology and the lapidary arts. We have monthly meetings at the Delaware Museum of Nature and Science, just north of Wilmington, Delaware. Our monthly meetings have speakers and programs that promote the goals of the society. We conduct several field trips a year to fossil and mineral localities in the tri-state area and further afield. DMS has close ties to other clubs in the Mid-Atlantic region that provide opportunities for some co-sponsored field trips. DMS is a member of the American Federation of Mineralogical Societies (AFMS) and the Eastern Federation of Mineralogical and Lapidary Societies (EFMLS).
