Become a vendor at the 43rd Annual Gem and Mineral Show, hosted by the Western Dakota Gem and Mineral Society in Rapid City. 

 

July 25-26, 2026 at the Central States Fairgrounds.

Hours: Saturday 9 AM - 5 PM, Sunday 9 AM - 3 PM

 

The 2025 event welcomed over 1,500 attendees, including local residents and visitors from outside the area, making it the best-attended show in the club's history. In previous years, the show was held exclusively in the Nerdy Nuts Expo Hall, but in 2025, it expanded into the GenPro building, offering more space for vendor booths and interactive educational exhibits.

​

A new feature this year will be Vendor Bingo. Attendees will receive a unique bingo card and must visit various vendor booths to collect stickers. A prize will be awarded to anyone who completes a full bingo card. This should encourage traffic to your booth should you become a vendor at our show.

 

The club actively promotes the show through local, digital, print, and community-based marketing efforts to ensure strong attendance and visibility. Review the documents below and secure your spot in the 2026 show!
