Toxicity of Rainbow Calsilica

    I have the same question about "rainbow calsilica" or "Duronite" as
    I think we should call it. I wonder about the presence of pigments
    such as the cadmiums which can be troublesome. 

    I just found a site on the web which references the composition of
    topcoat automotive paints. Among the pigments used are the lead
    chromates (yellow, oranges, etc.) and iron oxides. If you're
    cutting/cabbing any of the "newly found gemstones" like Detroitite,
    calsilica, or whatever, watch out for the inhalation of these
    pigments, or transfer through the skin.
