An incredibly large, sharp crystal of this very rare species found in only a few small pockets over all the years at MSH. It was in fact self-collected by the incredibly persistent collecting couple, Marcelle and Charles Weber, and remained in their collection since 1980 (I obtained a small suite of some of the top rarities in display size). At approx 1.5 x 1 cm, this is large for the species. Moreover, it displays really nicely atop contrasting matrix. It has a lustrous, red-brown color to it. It is terminated on the left end, contacted on the right. I would guess this to be among the largest of the species, though I have rarely seen larger (not on matrix). Certainly, its significant and as good as most of us will ever see.
