Pearceite is a silver arsenic sulfosalt mineral. Jaroslav Hyrsl imported these specimens during the Tucson 2008 show. These pearceite specimens have very attractive, lustrous groups of six-sided plates. These specimens came from a single pocket at the locality. I bought three of six specimens available; this is the best example I purchased. Pearceite has a structural relationship with polybasite. The largest pearceite crystal measures 7 mm across, and the largest proustite crystal reaches 8 mm. This is a rare opportunity to obtain a very fine pearceite specimen.
