2026 Denver Gam and Mineral Show: Red, White and Blue Show theme:
The 2026 Denver Show theme is based on Colorado at 150 years of statehood and the
1876 declaration of United States independence at 250 years. With a theme like this,
exhibits can be based on minerals of color, historic specimens exhibited in the far past or
specimen sold by historic U.S.A. dealers. For fossil collectors, the bone wars (including
the volcanic lake bed sediments of Florissant or Kremmer, Wyoming) of the late 1800s
also provide historic display opportunities, All of these choices are great opportunities for
unusal and attractive exhibits.
The colors of the USA flag inspires red, white and blue minerals. For Colorado,
we can choose rhodochrosite from Alma and spessartine from Ruby Mt., analcime from
Table Mt. and milky quartz from Ouray, and for blue, aquamarine from Mt. Antero and
barite from Stoneham. Within the United States the mineral choices are even better. Red
minerals are well represented by spessartine, and elbaite from the San Diego County
California pegmatites. White minerals can be shown by moonstone and cleavelandite
albite from Amelia, Virginia and moonstone from Rabb Canyon, New Mexico, calcite
from Ohio, and analcime from the trap rock quarry in New Jersey. Blue minerals can be
represented by benitoite from California, azurite from Arizona, lazurite from Georgia,
and topaz of central Texas.
Minerals of historic United States provenance would also be of appeal, such as
those shown at the Centennial Exposition of 1876 in Philadelphia. These minerals would
include Arkansas rock crystal, Colorado Amazon Stone, pegmatite minerals of New
England, zinc and gangue minerals from Franklin and Sterling Hill, New Jersey, and
traprock minerals of New Jersey and central Connecticut. With USA minerals exhibited
at successive later World Fairs, there would be no shortage of historic specimens.
Famous expositions held after the 1876 Centennial Exposition, Philadelphia,
Pennsylvania include:
1881 International Cotton Exposition, Atlanta, Georgia
1883 American Exposition, Boston, Massachusetts
1885 New Orleans Exposition, New Orleans, Louisiana
1893 World’s Columbian Exposition, Chicago, Illinois
1895 Cotton States and International Exposition, Atlanta, Georgia
1901. Pan-American Exposition. Buffalo, New York
1902 Charleston Exposition, Charleston, South Carolina
1904 Louisiana Purchase Exposition, St. Louis, Missouri
1905 Lewis and Clark Exposition, Portland, Oregon
1909 Alaska-Yukon-Pacific Exposition, Seattle, Washington
1912 Panama-California Exposition, San Diego, California
1915 Panama- Pacific International Exposition, San Francisco, California
Specimens sold by historic mineral dealers can form another subset of display
quality minerals. This would include specimens sold by A. E. Foote, George L. English,
Henry A. Ward or George F. Kunz. Colorado historic dealers include Lazard Cahn, Jesse
Randall, Ed Over, J. G. Heistand, Woodend, and many others.
About the Denver Gem & Mineral Show
In the 1950s, different gem and mineral clubs and societies put on their own Gem and Mineral show, but in the 1960s the Denver Gem and Mineral show was born when the organizations combined their small shows into one.
The Denver Gem and Mineral Show, which began in 1967, has grown over the years into the second largest show in the United States and has numerous satellite shows that have sprouted up around the area. Through the time the show has been developing, exhibits from a number of regional and national museums have remained key attractions along with other activities.
​
The Greater Denver Area Gem & Mineral Council is a non-profit 501(c)(3) corporation organized exclusively for charitable, educational, and scientific purposes.
