Colorado's Premier Gem Event
Every September, Denver becomes the second most important stop on the global gem and mineral circuit. The Denver Gem & Mineral Showcase draws approximately 1,000 vendors to multiple venues across the Denver and Westminster area, attracting buyers, collectors, and dealers from around the world.
The showcase is anchored by the Hardrock Summit at the Westin Westminster, which serves as the main event with both indoor and outdoor exhibition space. Additional major shows at the Denver Coliseum and other venues expand the range of offerings from fine mineral specimens to rough material, fossils, and finished jewelry.
For wholesale buyers who have already hit Tucson earlier in the year, Denver offers a second major sourcing opportunity with different vendor rotations and fresh inventory. Many dealers use Denver to debut specimens they've prepared since the Tucson season.
Denver is particularly strong for fine mineral specimens and fossils from Colorado and the Rocky Mountain region. If you're building inventory in Colorado rhodochrosite, amazonite, topaz, or aquamarine, this is where you'll find the best selection directly from regional miners and collectors. The Spring Show in April is a smaller but excellent opportunity to source material before the main September event.
