The Wyoming State Mineral and Gem Society (WSMGS) is a non-profit umbrella organization formed to bring about a closer association of Mineral and Gem Clubs and Societies in Wyoming. WSMGS has as its purpose the education, promotion, and development of interest in and understanding of the Earth Sciences, Lapidary Arts, and related fields both for affiliated clubs and their membes and for the general public. WSMGS Member Clubs are located in Big Piney, Casper (Mills), Cheyenne, Cody, Powell, Riverton, and Torrington, Wyoming.

Wyoming is an extraordinary state for rockhounding. We invite you to explore our website for information about Wyoming's minerals, rocks, fossils, and gemstones as well as for an introduction to the people and places where rockhounds can visit, explore, and learn.
