Dallas Mineral Collecting Symposium


August 22-24, 2025

Online Access to DMCS 2025

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.
