- Himmelsfurst Mine, Brand-Erbisdorf, Freiberg District, Erzgebirge, Saxony, Germany
Proustite old-time, very fine thumbnail from the historic Himmelsfurst Mine at Freiberg features sharp, lustrous, elongated, terminated proustite crystals. The lighting highlights the classic, deep wine-red "ruby silver" color of the blocky crystals. Ex. Sam Nasser Thumbnail Collection and certainly over 100 years old.
