RockFest, the annual event that features a combination of gem and mineral shows paired with activities for the whole family, kicks off the summer in style, June 8 and 9.
This year is shaping up to be one of the biggest and best with close to 30 dealers selling a variety of gems, minerals, fossils, jewelry and more. Vendors from all over the country will be showcasing incredible specimens from across the globe as well as unique jewelry and other items. RockFest is a perfect place to get some holiday shopping done early.
Check out the full dealer list, including ones offering member discounts!
Most of the vendors will once again be offering a special discount to Tellus members. Visitors to RockFest can expect to see a wide range of items for sale, from $2 rocks kids will love to collect, up to beautiful rings and necklaces that can’t be found in a regular jewelry store.
RockFest takes advantage of the usually great weather with dealers located outside the museum as well as inside the banquet halls. The Tellus Café will also have lunch available for purchase outside and the member hospitality area will be the perfect place to take a break and get out of the heat.
Got a rock you can’t identify? No problem! Stop by the Mineral and Fossil ID table and find out if you’ve got a meteorite, a dinosaur tooth, or another treasure. Expect to spend nearly a full day at RockFest, thanks to the always engaging activities aimed at youngsters. New this year is an outdoor rock wall where kids and adults can climb and defeat their fear of heights.
Other activities available: Rock Bingo – with prizes to all the winners, color a cloth Tellus collecting bag, or decorate a photo frame with gems and more.

The planetarium will feature a special schedule all weekend, and there will also be special door prizes given away every hour. A special grand prize will be raffled off in the banquet halls near the indoor dealers. Don’t worry ‑ you don’t have to be present to win.
RockFest has a long history at Tellus Science Museum. It was held for nearly two decades at the Weinman Mineral Museum before the museum expanded and became Tellus. Discover why nearly 3,000 people return every year to an event that’s more than just a “rock show.”
