Gratonite (rare Lead-As Sufosalt)
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 3-5 mm sized individuals. The Gratonite has the dull to slightly lustrous lead-silver color that is classic for these.
