- Machacamarca Mine, Machacamarca, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia
- Miniature, 4.3 x 2.6 x 2.4 cm
This specimen was collected very recently (within the last few months - 2009). It hails from one of the most exciting Bolivian locality of the last 10 years. This specimen features an attractive, sharp, tabular, metallic, silvery-grey color crystal measuring 2.2 cm with great form and sharp faces sitting on matrix. For the quality, these new specimens have created a lot of excitement, so much so that one of the best pieces was featured on the cover of the March/April 2009 Issue of the Mineralogical Record. This specimen is from the same mine and possibly the same exact pocket as the cover specimen.
