Description:
Under shortwave - 1st picture - bright yellow phlogopite crystals on a backdrop of reddish fluorescing calcite, bluish gonnardite. Under longwave areas of what may be hauyne fluoresce a nice yellow/orange, but this initial ID may be suspect. Investigations have shown that this may be hauyne altering to gonnardite, but the jury is still out.
