Small Cabinet, 6.0 x 4.5 x 3.5 cm
Colavi Mine, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia
This is a good example of the rare antimony oxide, Valentinite. The piece features sharp, lustrous, translucent to gemmy grey/colorless colored, fine quality, tabular crystals of Valentinite measuring up to 7 mm (good size from this mine) on massive Galena. This specimen was mined 6 years ago, and I have not seen any more specimens from this mine since that time.
