Gem and Jam Festival 2027 runs Friday, February 5 to Sunday, February 7, 2027 at the Pima County Fairgrounds, 11300 S Houghton Rd, Tucson, AZ 85747, and the official about page says it is the festival's 18th year. It is timed to the Tucson Gem, Mineral and Fossil Showcase, which the festival says brings over 55,000 visitors to Tucson over three weeks. Since its 2026 return, it has been presented with the Arizona promoter Relentless Beats. The official FAQ lists festival-ground hours of 11 AM to 4 AM on Friday and Saturday and 11 AM to 3 AM on Sunday, and the event is all ages.
The 2027 lineup is out and is topped by Ganja White Night. The official lineup page and the billing graphic on the official site add Balkan Bump, Blu DeTiger (DJ set), The California Honeydrops presenting Sweet & Sticky After Dark, Daniel Donato's Cosmic Country, Eazybaked, Josh Teed, Lotus, Mark Farina's Mushroom Jazz Jam, Ott., Player Dave, Richard Finger, Russ Liquid, Saka, Shiba San, Skysia, Smoakland and a Wreckno sunset set, with 43 acts in total and an ALL:LO takeover by Parkbreezy, Pheel., TF Marz and Alex Unger. The lineup is not split by day, and stage names and set times had not been posted as of October 3, 2026.
Pima County Fairgrounds sits on the southeast edge of Tucson, about 20 miles from downtown according to Visit Tucson, and Gem and Jam uses it as a full camping festival: free walk-in camping comes with the weekend pass, with car camping, RV and glamping sold separately. The official FAQ lists free showers inside the festival grounds on the way to the Cantina, free water stations, an ATM, and food vendors with vegetarian, gluten-free and vegan options. What sets it apart is the mix: bass and house DJs share the bill with live funk, jam and country-fusion bands, plus workshops, live painters, healers and art installations, all tied to the gem and mineral theme.
