Fluorescent Pair-3
Clay Center, Ohio

The first view is a mineral observed under normal light,
while the second is the same mineral
viewed under ultraviolet light.

The fluorescent mineral is fluorite.  Under normal light, the fluorite is
root beer brown, but under the ultraviolet light it fluoresces a pale
yellowish color.
