A Little About Us

Picture
The Chesapeake Gem & Mineral Society is a Baltimore, MD based non-profit organization whose members share an interest in gems, minerals and fossils and rocks to name just a few. We are a  member of the Eastern Federation of Mineralogical &  Lapidary Societies (EFMLS) and affiliated with the American Federation of Mineralogical Societies (AFMS).

Our meetings normally include either a featured speaker or an auction (March and October). Visitors are always welcome!  Field trips are arranged for the warmer months, and we sponsor a one-day gem and mineral show in April.   Our monthly club bulletin, Chippers' Chatter, provides information about club activities and includes educational articles.
