Here are some crude, grayish white crystals in calcite that appear to be a mineral in the apatite group that strongly fluoresce yellow-orange under SW. This one has weak orange LW color so is probably not hedyphane, which is supposed to be weak white under LW. The crystals here appear to be primary and hedyphane is a secondary. Johnbaumaite and mimetite also dont seem right based on descriptions in Dunn. But turneaureite is a distinct possibility, the color and fluorescence is right and it is associated with andradite and magnetite as noted in Dunn. 8 cm across

Looks like a rich turnueareite specimen but Johnbaumite could also be a possibility.

Often turnueareite is accompanied by andradite

This piece has andradite and magnetite (firmly held a magnet upside down) as noted by Dunn, so going with turnueareite.
