Here are three photos of the special TGMS display case that was next to the Franklin and Sterling Hill -American Mineral Treasures display case. The fluorescent case was modified just for displaying fluorescent mineral in high ambient room light in the Tucson Convention Center. This case has four special SW TripleBright II UV lights and a cantilevered black cloth covering for the top and sides. Most of the specimens are from the personal collections of Richard C. Bostwick and Earl R. Verbeek, with some from the Sterling Hill Mining Museum. This was undoubtedly the finest single display case of fluorescent minerals since Tucson ’96 when there were 76 cases of fluorescent minerals at the TGMS Show.

 

Fluorescent Minerals of Franklin and Sterling Hill, New Jersey

The two zinc deposits at Franklin and Sterling Hill, New Jersey, have produced some of the finest examples of mineral fluorescence in the world. What makes these localities so great? Consider the following:

  • Large number of fluorescent mineral species: 89 at last count.
  • Bright, bold, and varied colors of fluorescence, with at least 20 species fluorescing brightly enough for display.
  • Presence in many specimens of two or more fluorescent minerals.
  • Large grain size and textural complexity of many mineral assemblages.
  • Fluorescent species rare or unknown elsewhere (hardystonite, esperite, turneaureite, clinohedrite, numerous others).
