Mineral Specimen #6088 Willemite, Franklinite and unidentified Fluorescent Species
Franklin Mine, Sussex Co., New Jersey
11.7 x 8 x 4 cm
The specimen is a bit of a mystery. One side is a typical mix of Willemite and Franklinite. Another side has a surface which has a bumpy, brown colored surface with a submetallic luster. This unidentified material is present as just a thin layer on this side. On another side, there is another unidentified material which varies a bit in color but is generally a peachy pink/orange. The big surprise here is this surface fluoresces a yellow/orange color under long wave. This does not match with anything I could find from Franklin.
Flaws: Essentially massive material.
