Item Number: MI74

Geodes are called “nature’s jewelboxes” because of the beautiful crystals that can sometimes be found inside these unique, globular quartz bodies. This CD-ROM contains an annotated PowerPoint presentation explaining the current theory about geode formation and how geodes change as they are exposed to weathering.
