Denver Gem & Mineral Guild

Founded in 1964, the Denver Gem and Mineral Guild is an award-winning non-profit organization that pursues exploration, experimentation, and education in the Earth Sciences; the discovery, development, and preservation of minerals and mineral deposits; and the advancement, encouragement, and utilization of the principles of art and craftsmanship, as applied to gems and minerals.  We are a diverse group of women, men, and children who love ROCKS. We love to dig them, cut them for jewelry, and collect them. Our members love to share our passion for rocks and minerals. We have professional geologists, teachers, lapidary artists, and people who just love rocks.

The Denver Gem & Mineral Guild is a member of:

The Greater Denver Area Gem and Mineral Council, Inc., host of the Denver Gem & Mineral Show™, is a non-profit 501(c)(3) corporation organized exclusively for charitable, educational, and scientific purposes. Trustees from each of our seven member clubs sit on the Council Board. The Council oversees the annual show, and twice each year, the Council distributed proceeds from the show in the form of grants to not-for-profit organizations, particularly those based in Colorado, to promote activities that educate the public in the earth sciences.

Annual giving ranged from $20,000 to $30,000. Funds were directed toward site and specimen preservation and display efforts, as well as to assist institutions in purchasing equipment, tools, and supplies. Recent grant recipients have included the Denver Museum of Nature and ScienceColorado School of Mines Geology MuseumDinosaur RidgeMorrison Natural History Museum FoundationHinsdale County Historical SocietyCanyon City Geology ClubBig Horn Basin Foundation, and the Junior Museum of Pennsylvania.

Since Covid, and the loss of our venue at The Mart, our new event at the Hardrock Summit continues to provide a showcase and outreach to the community, as we work on returning to profitability.

The Rocky Mountain Federation of Mineralogical Societies has a close association with all the clubs in the Society to promote the study of earth sciences, including the lapidary arts, the study of fossils and paleontology, and related crafts.

The RMFMS was organized in 1941, and held its first annual convention at the Argonaut Hotel in Denver, Colorado. There were 16 organizations in attendance. The RMFMS became one of the original four founders of the American Federation of Mineralogical Societies when it was organized in 1947.

The Rocky Mountain Federation of Mineralogical Societies covers local clubs in the following states:

Arizona (17), Arkansas (1), Colorado (20), Kansas (5), Nebraska (western portion of state) (1), New Mexico (7), Nevada (1), North Dakota (western portion of state)(1), Oklahoma (9), South Dakota (western portion of state) (1), Texas (1), Utah (7) and Wyoming (7).

For more on the early history of the RMFMS, check out History of the Rocky Mountain Federation of Mineralogical Societies 1941 – 1963 by Muriel Colburn.

The American Federation of Mineralogical Societies promotes popular interest and education in the various Earth Sciences, and in particular the subjects of Geology, Mineralogy, Paleontology, Lapidary and other related subjects and sponsors and provides means of coordinating the work and efforts of all persons and groups interested therein. It sponsors and encourages 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.

The American Federation of Mineralogical Societies is composed of the following seven similar regional organizations of gem, mineral, and lapidary societies.  CFMS – California Federation of Mineralogical Societies | EFMLS – Eastern Federation of Mineralogical and Lapidary Societies | MWF – Midwest Federation of Mineralogical and Geological Societies |  NFMS – Northwest Federation of Mineralogical Societies |  RMFMS – Rocky Mountain Federation of Mineralogical Societies |  SCFMS – South Central Federation of Mineral Societies
