As of 2025, we have decided to forgo the livestream ticketing option for the Dallas Mineral Collecting Symposium. In place of the livestream, we intend to make all presentations available to the public free of charge in the video showcase portion of our website shortly after the conclusion of the symposium.
Our annual Symposium Benefit Auction will be featured here when launched and live!
Check mineralauctions.com, complete with dozens of minerals, mineralia, and mineral collecting field trips.
The 2026 DMCS benefit auction will begin at least a week prior to the symposium and will end at 6:00 PM CDT on Saturday, August 22, 2026. You do not need to be present at the symposium to participate in the auction.
Big thank you to all our donors and bidders for helping make a difference in the mineral community year after year!
