A rare, very rich solid specimen of metallic-bright, brassy, hexagonal nickeline crystals to 3 mm nicely accented with baryte on this fine, old-time piece from Eisleben, Germany. Nickeline is the combination of the two elements, nickel and arsenic. Accompanied by an old, handwritten German label. The collection this came out of was a museum stash dating to prior to World War I.
