Gratonite (rare Lead-As Sufosalt)
stock #13.1-379
Excelsior Mine, Cerro de Pasco, Pasco Province
Pasco Department, Peru
5.4 x 3.2 x 2 CM (small cabinet/large miniature)
price: $400
Spring 2014

Gratonite when available is usually in thumbnail sized pieces. This is a more sizable piece and well crystallized. The best were found over 50 years ago and Pasco is the only source for fine specimens. Branching crystal aggregates to 2.5 CM cover most of a sulfide matrix, composed of 3-5mm sized individuals. The Gratonite has the dull to slightly lustrous lead-silver color that is classic for these.
