The minerals in the specimen are calcite, willemite, and franklinite, from Franklin, New Jersey.

The first image was taken under a short wave ultraviolet light. The calcite fluoresces red to red-orange, willemite fluoresces bright green, franklinite does not fluoresce at all (it will be the black areas). An added bonus with New Jersey specimens is that the willemite in the specimen will phosphoresce for a short while after exposure to short wave ultraviolet light, when the lights are turned off in a dark room.

The second image below was taken under long wave ultraviolet light. The pinkish color is the long wave light reflecting off the light colored calcite which does not fluorescence under long wave. The willemite fluoresces lightly under long wave ultraviolet light. Franklinite does not fluoresce at all and will appear as a black area on the mineral.
