For over 50 years, OGMS has hosted a fall Rock, Gem & Mineral Show.

The Show consists of vendors and exhibits that further our club mandate to study and promote an interest in earth science, geology, paleontology, and mineralogy; study lapidary and jewelry-making art; conduct education; support youth activities; and encourage interest in earth science.

This show is held on the 4th weekend of October (October 28-29, 2023) at the Springfield Expo Center on East St. Louis Street in Springfield, Missouri. Our club is a state & federal non-profit, and the gate at the show is our yearly major fundraiser.

NO WEAPONS. Service Dogs Only.
