The 2025 Mineral, Gem, Fossil Show & Sale, presented by St. Louis Mineral & Gem Society, is coming to Affton Community Center, 9801 Mackenzie Road, on November 21st, 22nd, and 23rd.
This annual show is a great place to shop for gems, minerals, crystals, fossils, jewelry, rock carvings and more! If you are looking for a truly unique, one-of-a-kind gift, this is the place to be! And if you are a rockhound, this is the place to find your latest treasure for your collection!
If you have any students interested in geology, this is a great place for them to see and learn about rocks, minerals, and fossils, and for children 13 and under there will be an area where they can make their very own rock starter kit to take home with them – for FREE!
There will be 15 dealers with a great assortment of rocks, beads, jewelry made with rocks and minerals, and so much more. Have you ever wondered what is inside a rock? Well, our geode cracker will be cracking open geodes to reveal the wonders inside – and you will be the first to ever see what is in that geode! This is a real treat for kids and adults!
And you can register to win a daily prize – a unique mineral that you will want to showcase in your home!
