Description:
Aragonite "lightning bolts" fluoresce bright blue/white on this spectacular specimen from the Long Lake Zinc Mine, Olden Township, near Parham, Frontenac Co., Ontario, Canada. Under visible light, this piece looks like an unimpressive chunk of white marble, but under longwave UV a storm of blue, white bolts dominate the display. This specimen is at its best however, when viewed under shortwave UV, showing not only the bright blue/white aragonite lightning bolts, but also a beautiful mix of pink/orange, fluorescent calcite, spots of yellow glowing chondrodite and blue dots of diopside.
