American Federation of Mineralogical Societies


To promote popular interest and education in the various Earth Sciences, and in particular the subjects of Geology, Mineralogy, Paleontology, Lapidary and other related subjects, and to sponsor and provide means of coordinating the work and efforts of all persons and groups interested therein; to sponsor and encourage the formation and international development of Societies and Regional Federations and by and through such means to strive toward greater international good will and fellowship.

Why Join a Club?

Rock clubs offer many resources to members including field trips where you can collect rocks, minerals, and fossils; lapidary workshops where you can learn how to cut and polish stones and make jewelry; educational activities for children and adults; and the opportunity to meet people who have the same interests as you! Clubs affiliated with the AFMS abide by the AFMS Code of Ethics, can acquire liability insurance from their Regional Federation, so members enjoy access to field trip locations that would otherwise be inaccessible.

Cacoxenite and Quartz

The fluffy yellow balls are cacoxenite, and the red crystals are quartz coated with iron. Each little ball is approximately 3mm diameter. This specimen was collected on a club field trip in South Carolina.
