- Zinkenite, Kaolinite
- Small Cabinet, 8.4 x 7.4 x 4.4 cm
- Itos Mine, Oruro City, Cercado Province, Oruro Department, Bolivia
Aesthetic diverging sprays of lustrous, flattened, black zinkenite crystals richly cover the 3-dimensional, platy, kaolinite matrix on this fine, rare, old-time specimen from the Itos Mine at Ouro City, Bolivia. This classic, seldom-seen combination specimen was collected by Sam Gordon on one of his several trips to Bolivia, Peru and Chile in the 1920s and 30s for the Philadelphia Academy of Sciences. The old label of "parakeeleyite" means that the zinkenite had not been correctly identified, when collected. Confirmed by analysis, on my end, via Bart Cannon's lab.
