Calcite Crystals and Fluorite, w/ Multi-Wave Response - Illinois Fluorospar District

Last year (2017) the midwest chapter of the FMS had their annual meetup in Marion KY, followed by an evening of collecting at the Minerva Mine in So. Ill. I showed off some Greenland rocks, lights, and stuff and later the entire group went on a tour of the wonderful museum. Since I had already been on the tour twice before I hung back and explored the gift shop with my UV light. Came across this beauty and picked it up since it fluoresced so nicely under SW. Had no idea what lay in wait under MW and LW! An exceptional specimen - very happy with this find.
