Welcome to the Gem, Lapidary and Mineral Society of Washington, DC
Our Society, GLMSDC, has been in existence for 65 years serving people in the National Capital Area who share a common interest in the Earth Sciences. We are a co-founder of the Eastern Federation of Mineralogical & Lapidary Societies (EFMLS). Since the EFMLS is a member of the American Federation of Mineralogical Societies, our members realize the benefits of both federations.
The GLMSDC promotes learning and interest in:
The Earth Sciences
The lapidary arts
Mineral and fossil collecting
Touring museums and other hobby-related sites
A fun-filled learning environment
Our Club offers lectures by experts in geology, minerals, gems, fossils and lapidary arts. Fascinating and timely topics are covered by university professors, museum curators, scientists, skilled artisans and authors of relevant publications. Members also present lectures about their areas of expertise and their field-trip expeditions.
Our Club organizes field trips, usually on weekends from March to November. Members collect at sites for beautiful crystals, minerals, fascinating fossils and lapidary cutting materials. Collecting sites are within a 200-mile radius of the Washington, D.C. area. We tour museums or view private collections.
