    Description

    Beautiful specimen of strontianite on calcite ,in limestone matrix, from Meckley Quarry, Mandata, Pa. Nice short wave and long wave fluorescence. Specimen displays brief bright phosphorescence upon withdrawal of the short wave UV lamp.
    The specimen is beautiful naturally ( photos 6 - 10)
    Photos 1 - 5 are under short wave with Super Bright Lamp. The specimen retains a brief bright phosphorescence when short wave lamp is removed ( Photos 2 & 4, bottom image). Any purple is reflected UV light. Also some phosphorescence long wave.
    The last two photos display long wave fluorescence which was taken with 36 watt Way Too Cool lamp.
    Please note special UV light /lamps mandatory to visualize the fluorescence. The stronger the lamp, the brighter the fluorescence!
