Fluorescent Mineral Specimen
Franklin Mining District
Sussex County
New Jersey, USA
3.41 x 2.23 x 1.83 inches (8.67 x 5.66 x 4.65 cm)

While rather unassuming in normal light, this nicely sized rock hides a vibrant secret. The Willemite majority of this specimen from the classic Franklin Mining District of New Jersey shines a neon green, fluorescent color under Shortwave Ultraviolet light, with flecks of orangey Calcite and black non-fluorescing Franklinite adding a contrast to the verdant palette over the rocky exterior. This is a surprising and fascinating offering that will delight all collectors and viewers alike.
