- Machacamarca Mine, Machacamarca, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia
- Small Cabinet, 6.5 x 4.5 x 1.4 cm
This piece features a few fine, sharp, lustrous, colorless, gemmy crystals of Augelite measuring up to 1.1 cm associated with minor octahedral Pyrite on matrix. The quality of the Augelite crystals is very good and they are certainly good sized for this mine. This rare phosphate mineral is not seen often in any format from any locality.
