    Description

    SHORT WAVE UV
    Nice specimen of Zinc ore from the Franklin Mining District. Fluorescent green Willemite along with non fluorescing Franklinite, Calcite and red Zincite.
    Nice UV specimen.
    Short wave UV is what you need for this one, it does fluoresce under long wave but not as well.
    From Franklin Mining District, Sussex County, New Jersey.
    71 grams.
    Just under 2-1/2" length
    NOTE!
    I used a 5 watt short wave lamp for the SW images, you will need the same or similar to see the fluorescence.
    I do combine shipping, so please request an invoice before paying.
    Zincite, Calcite, Willemite and Franklinite Marble. Sterling Hill Mine, New Jersey.
