Fluorescent and Phosphorescent Calcite, Annabel Lee Mine, Cave-In-Rock, Illinois


This is a subtle, but beautiful fluorescent specimen from a classic Cave-In-Rock, IL, location-  the Annabel Lee Mine.  Comprised of a cluster of off-white calcite crystals on a limestone/dolomite matrix, this piece shows a similar fluorescent response under all wavelengths of UV light.  It fluoresces a lovely yellow/blue with green phosphorescence, but shows the brightest response under LW.  The size of this specimen is 83 x 62 x 41 mm, and weighs 172 grams.
