This hand specimen consists of a chalky, pale brown sandstone host rock on which rest several small, very thin crusts of massive Andersonite. Even under 10-power magnification I cannot detect any crystal form or crystalline tendencies. The crusts have a bright yellow color with a hint of green and a dull waxy luster. When bathed with shortwave ultraviolet radiation, the Andersonite glows a bright pale blue-green coloration. There are several patches of this material scattered around the host rock.
