    Description

    Beautiful Grey/Blue Chalcedony/Chert fragment that fluoresces a nice yellow under a good long wave UV light (365nm). Nice sample.
    Found in Milwaukee County Wisconsin along the lake Michigan shoreline.
    I am not certain of the reactive element that causes it but possibly a carbonate mineral.
    90 grams
    2-3/4" in length.
    NOTE!
    Photos taken with a 365nm Convoy2 band pass filtered Long Wave UV light, if you use any other type of UV light you may get different results.
