Psilomelane - iridescent, on Barite
Aouli. Midelt, Khenifra Province
8.8 x 5.8 x 4.2 CM (cabinet)
Early summer 2021
A complex stalactitic and botryoidal growth of Psilomelane on Barite with colorful iridescence. This looks otherworldly in person like something in a science fiction film. The dark masses of Psilomelane have both a dull and a metallic luster that is impressive with bright lighting. This contrasts well with the cream colored Barites. From Aouli in Morocco, this was in the John Marshall collection since 2000 and is one of the best examples I have seen of the specie from that region.
