The external surface of the Nickeline is coated in Acanthite with minor wires of Native Silver and a rare crystal area of Polybasite measuring to 4mm. Exposed areas of the Nickeline displays a metallic pink colour and radial structure. A very fine Acanthite-Nickeline specimen from Medenec, Czech Republic.
