The Cureton label this specimen came with identified this as the rare barium chromate, Hashemite. I am not sure about that identification, so a labeled it just Ettringite, which are the radial white spheroids. In the center of a few of these opened spheroids are a yellow mineral which is just to tiny for me to have confidence as Hashemite.
