A micro-mineral delight from the Tsumeb Mine. Small brown platy russet crystal groups of super rare Ferrilotharmeyerite. The Ferriltharmeyerite is associated with yellow hemispheres of Chenevixite to 1mm (another rare species for Tsumeb Mine). Lightly scattered amongst these two minerals are micro-crystals of Silver. Yet another supergene mineral on this stunning thumbnail specimen are bush like growths of deep green olivenite to 3mm. All the above minerals have formed on a crystalline light green Cuprian Adamite. The matrix for the array of secondary species is a Germanite. A very rare and interesting specimen to study.
