Description

Definitely an uncommon sight, a piece of rich silver ore from a historic gold mining district of Australia. Most obvious is nicely tarnished, reddish wire silver while secondary phases recorded on the label are altaite (small, black crystals in a vug) and petzite (blocky, silvery white crystals). More minerals are likely present on this little interesting specimen.
