Miner's Co-Op Rock Show

The Miner’s Co-Op Rock Show returns to Marana at Sports Park Tucson, bringing together one of the world’s largest agate collections alongside an incredible selection of gemstones, minerals, fossils, jewelry and geological treasures from around the globe. Held annually during the Tucson Gem, Mineral & Fossil Showcase, this free event is open daily from late January through mid-February and offers visitors the chance to shop directly from the miners, rockhounds and artisans who personally source or create everything they sell.

Known as the "Home of the Doers and Diggers," the show features dozens of passionate vendors with firsthand knowledge of their collections. Whether you're a serious collector, jewelry enthusiast or simply curious about the beauty of natural stone, you'll discover colorful agates, sparkling crystals, unique fossils, handcrafted jewelry and one-of-a-kind mineral specimens.

Families are welcome to enjoy free daily giveaways for kids, free parking, a daily food truck and special attractions like Bigfoot's Cabin, an imaginative display featuring artwork painted on rocks. With friendly experts eager to share their knowledge and an unmatched variety of natural treasures, the Miner’s Co-Op Rock Show is a must-visit experience for gem and mineral enthusiasts visiting Marana.

Miner’s Co-Op Tips: Bring cash. Many vendors accept credit or debit cards, but several do not, and there are no ATMs on site. Plan to spend several hours exploring the show’s expansive collections. The event is pet-friendly. Admission and parking are free.
