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, and people who just love rocks.

We meet the 2nd Friday of the month – September through May at the Colorado School of Mines in Berthoud Hall room 108 at 7pm – VISITORS WELCOME!  – CLICK HERE for details.

December 2020 Program

Here is the replay of our DGMG December 2020 meeting, where we  continued our exploration of 3D, this time examining how to create 3D computer models. Shellie (paleogirl) Luallin from the Western Interior Paleontological Society (WIPS) was our presenter. Shellie has practiced her 3D photogrammetry expertise on specimens of vertebrates and invertibrates. She has done images of a wide range of ammonite specimens. See her web site and have fun rotating a Didymoceras – it takes practice, but WOW! Check out her work at SketchFab.com/Paleogirl.

Join the Denver Gem & Mineral Guild!

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 eight member clubs sit on the Council Board. The Council oversees the annual show, and twice each year, the Council distributes 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 ranges from $20,000 to $30,000. Funds are 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.

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).

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
 |  SFMS – Southeast Federation of Mineralogical Societies
