Really not too sure which Arrojaite this is, but likely it is Arrojadite-(KNa). It is dark olive green, translucent with sub-parallel tabular crystals stacked with roof-like terminations. Either which way the crystals are excellent and are not found in pegmatites like well crystallized. It is rather, a black shale phosphate.
