The Eastern Federation of Mineralogical and Lapidary Societies, Inc. was organized in 1950 as a nonprofit to bring about a closer association of Mineral Societies devoted to the study of geology, minerals, earth sciences and the practice of the lapidary arts and related crafts in the eastern portion of the United States.
Beginning with three “founding” mineral societies and seven “charter” societies, the EFMLS has now grown to approximately 115 affiliated societies, with a combined membership of approximately 9,200 individuals.
The EFMLS is a member of the American Federation of Mineralogical Societies, the umbrella association for the seven regional federations in the United States. The EFMLS joined the AFMS in 1952. See the other 7 regional federations listed below.
