Stephanite from Freiberg dist., Erzgebirge, Saxony, Germany
Silvery prismatic, unusually lustrous Stephanite crystal 2.5cm long, nicely terminated and set-off nicely by white drusy Quartz. The specimen sits naturally perfect without aid. I recall an article by Dr. Terry Wallace, which mentioned that Stephanite usually does not hold its luster over the years. Looking at photos in-print, all have a duller luster than this specimen. Carries an original Brian Loyd Minerals tag.
