- Miniature, 5.0 x 4.4 x 2.3 cm
- Colavi Mine, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia
This is a fine example of the rare Antimony Oxide, Valentinite. The piece features sharp, fine, lustrous, pale straw color, prismatic crystals of Valentinite sitting atop massive Galena. This specimen was mined 8 years ago, and I have not seen any more specimens from this mine since that time. The largest crystal measures 9 mm long, which is very good size for this locality.
