No, no Millerite on this specimen. But it's a true gem out of the Charles Noll collection. Apparently he bequeathed his collection to Maquette University, who promptly spun it off to the market. Be careful who you donate your collection too!
I guess I shouldn't complain. This specimen has a large pocket lined with platy Hematite and water clear Quartz. The large white balls are aggregates of Dolomite to 1cm. Mineralogically, a simple specimen but naturally perfect with good contrast of white on black. Very hard to get any specimens from this long classic locality.
