This is a classic fluorescent, specimen from the famous Franklin Mine inFranklin, Sussex Co., New Jersey. Thislarge piece is from the collection of Marv and Kitty Starbuck, and consists ofcalcite and willemite, with minor franklinite and other minerals. It has a single cut surface and the remainderis the natural rough. Under short waveUV (254nm) the calcite fluoresces red/orange and the willemite green. The franklinite is not fluorescent. This specimen mea...sures approximately 3.5 x4.4 x 3.2 inches, and weighs 2.6 pounds. The fluorescent photograph was taken using an 18 watt short wave (254nm)UV lamp.
As is the case with all fluorescent mineral specimens, a good quality UV lamp of adequate output and appropriate wavelength (short wave vs. long wave) is required to see the fluorescent response depicted in the photographs. An ordinary "black light" will not work for these minerals.By request, I will combine shipping on multiple items and for multiple winning bids within 7 days.
