||Acanthite with Polybasite
Uchucchacua Mine, Oyon Province
Lima Department, Peru
2.9 x 1.6 (thumbnail)
A very nice Silver thumbnail. Sharp for the locality and for the specie, this is a lusterous aggregate of highly modified Acanthites that are basicly dodecahedral. There are bright and sharp up to 5mm crystals of Polybasite nestled between the larger Acanthites. Associated with Pyrite, this is very good for the locality.
