Strontianite, Winfield, Pennsylvania

Radiating clusters of acicular crystals of off-white colored strontianite from the Winfield Quarry, Winfield, Union Co., Pennsylvania.  The Winfield Quarry is notable for producing fine quality fluorescent strontianite specimens.  This example fluoresces blue/white under short wave UV and warm white long wave UV.  It is also briefly phosphorescent under all wavelengths, most brightly under short wave UV.  This specimen measures 37 x 28 x 18 mm, and weighs 12 grams.
