Beautiful 3-Color Rock from Franklin, New Jersey


This is a truly classic 3-color fluorescent rock from the Franklin Mine, Franklin, New Jersey, that provides a spectacular example of why Franklin is known as the Fluorescent Mineral Capital of the World.  This specimen contains light colored hardystonite, willemite and calcite, and dark olive/brown andradite garnet.  Under short wave UV, the hardystonite fluoresces blue, the willemite bright green, and the calcite red/orange.  The andradite is not fluorescent.  The size of this specimen is 6.4 x 6.0 x 4.8 cm, and it weighs 268 grams.
