>     The chemical name for Turquoise is Aluma Phosphate

    News to me. Is "aluma" even a word? 

    Seriously, according to Pough's Field Guide to Rocks and Minerals,
    turquoise is "hydrous basic aluminum phosphate plus copper," and is
    sky blue to light greenish blue. With no copper, I believe we would
    be talking about "hydrous basic aluminum phosphate, AKA wavellite.
    Wavellite can be white. But it ain't turquoise. 

    I also saw the "aluma" rap on Yandre and Teague's website. There
    oughta be a law....
