Fluorite Crystals | The Story of Illinois
Fluorite crystals formed 150–200 million years ago when hot water containing fluorine and other minerals was forced up through cracks in the earth where it interacted with the calcium-rich limestone bedrock. Crystals formed along cracks and in other open spaces in the rock. Fluorite (fluorspar) mining got its start in Illinois in 1842.
