A classic and superb, two-sided, Panasqueira arsenopyrite specimen from the Dave Stoudt Collection. Sharp, metallic-bright, intensely striated, tabular arsenopyrite crystals in parallel-growth are beautifully accented with a scattering of gemmy and lustrous, colorless, hexagonal apatite crystals near the terminations. The Stoudts purchased this piece in 1985, according to their catalogue.
