Hardrock Summit has rapidly established itself as the anchor event of Denver Gem Show Week, drawing wholesale buyers from across North America to the Westin Westminster each September. With over 450 vendors spread across indoor exhibition halls and outdoor tent spaces, the show delivers broad coverage of rough gemstones, mineral specimens, fossil collections, and finished jewelry at competitive wholesale pricing. The indoor portion runs September 10-13, while outdoor dealers extend through September 18, giving buyers flexibility to plan multi-day sourcing trips alongside the co-located Denver shows.
For wholesale buyers, Hardrock Summit offers a compelling alternative to the Tucson circuit. The free admission model with pre-registration keeps overhead low, and the concentrated vendor layout at the Westin Westminster makes it efficient to compare inventory across hundreds of dealers in a single venue. Expect strong selections of Colorado-sourced specimens, rough material from international suppliers, and an increasing presence of lapidary equipment dealers. The show’s proximity to other Denver Gem Week events at the Denver Coliseum and National Western Complex means buyers can cover the entire Denver market in one trip.
Whether you are stocking retail inventory, sourcing rough for cutting, or building relationships with international mineral dealers, Hardrock Summit delivers the vendor density and product diversity that serious wholesale buyers need. The Westminster location offers easy access from Denver International Airport and ample hotel options along the US-36 corridor.
