Clarke Gem and Mineral Collection

Collected over her lifetime by Cecile Clarke, the gem & mineral collection at the Clarke Museum contains both local and non-local specimens. In addition, we have a display of local seashells donated to the Clarke by Ralph Ferguson and Robert Talmadge.
Currently, our rock and mineral collection is in the process of being relabeled by museum volunteer Jason.
