The colorful pattern of fluorescent calcite (FL red) & willemite (FL green) from New Jersey is printed on this mug! The photographic image of this mineral specimen is from the collection of Jim Horste. The mineral itself came from the famous mine in Franklin, New Jersey. Note that the image is a NON-fluorescent photographic transfer of what the mineral looks like under black light. The mug itself does NOT fluoresce under black light.
