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.

 

HAPPY DANCE!

April 2021 Program

Our program for the April meeting was a pre-recorded interview about minerals and specimen mining. The speaker was Joe Dorris, of Pinnacle 5 Minerals, and operator of the Smoky Hawk and adjacent amazonite claims and the Gem Mountain topaz mine.
This presentation was from the Mineral Talks Live series. Produced by BlueCap Productions, run by Ed Swoboda, the series features weekly discussion and show-and-tell presentations by curators, mineralogists, dealers, and collectors worldwide. The series is hosted and “emceed” by Ed plus museum curators Dr. Eloïse Gaillou, Paris School of Mines, and Dr. Raquel Alonso-Perez, Harvard University Mineralogical and Geological Museum.
The interview with Joe was originally aired live on February 17, 2021, and was the 35th in the Mineral Talks Live series. Ed described Joe as “Gentleman, miner, father, husband, grandfather, author, artist, award-winner, and television star.” The interview focuses on Joe’s amazonite mining, as well as his background in general.

Here is the lineup of coming events. Check out the latest DGMG Newsletter for additional details.

DGMG Meeting – 7 p.m. May 14, 2021 – The Complex Mineralogy of Agates by Dr. Peter Heaney, Penn State University

Meeting ID: 867 3248 0339           Passcode: 021553

“How do agates form?” has always a highly puzzling question, and that’s what Dr. Heaney addresses in this talk. Since the presentation will be about agates, we’ll invite everyone who attend, to have handy, one of more of your own “most interesting” (or most informative, or most puzzling) agate specimens, and after the talk we can all show them to each other!

“The Sinkankas Symposium has been described as the most important gemological conferences in North America. The annual event is named for John Sinkankas (1915–2002), one of the most distinguished and influential figures in gemology and mineralogy. Every year, presentations on a featured gem theme are given by specialists in diverse gem-related disciplines. The Sinkankas Symposium is co-sponsored by the Gemological Society of San Diego (GSSD) and the Gemological Institute of America (GIA) .”

FIELD TRIP #2 SATURDAY MAY 15. Phoenix Gold Mine, Idaho Springs, CO

This little hole in the ground is world famous! Dave, Becky and Becky’s brother have made some major changes at the mine. Come with us on this field trip to see the changes, go underground and see gold veins IN PLACE, and then pan for gold in Trail Creek. Normally $24, this tour will be FREE for all dues paid DGMG members. Full details are in this month’s newsletter. (This trip alone is worth more than the cost of your annual DGMG dues! To learn more about membership in the DGMG click here.

 

And while you wait for this trip, check out this additional video created by Beth Simmons about the mine, the Mosch family and lots of local history.

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
