A direct-from-the-source provider of quality geode and mineral specimens since 1995, Geode Gallery, LLC is owned and operated by Mike Sandstrom, who collected his first geode at the age of 8. Today, Mike maintains the Geode Gallery website, travels to rock, gem, and mineral shows across the country, and actively mines Keokuk geodes, the Geode Gallery’s specialty!

Mike invites you to browse his updated website both for geodes and for geode-related educational information and hopes you will find everything you need. If not, just ask!
