    Description

    LONG WAVE and SHORT WAVE UV
    Nice two color fluorescence with this Terlingua-type Calcite cleaved rhomb. It fluoresces a pink with long wave UV light and blue under in short wave UV light.
    Very strong Phosphorescence after short wave UV exposure wave.
    The crystal is cleaved into a typical Calcite rhombohedral form and is a milky white to clear in color.
    These Terlingua type Calcites are amazing, probably the best fluorescing minerals I have owned.
    From The Challenger Cave in Nuevo Leon, Mexico.
    65 grams.
    2" inches in length.
    NOTE!
    I used a long wave (365nm) UV convoy2  with a band pass filter for the long wave images, you will need one as well to see the UV reaction like in the pictures.The short wave images were shot under a 6 watt short wave lamp (254nm).
