Chalcodite is an OLD-TIME synonym for stilpnomelane. This CLASSIC and HISTORIC New York piece is from the famous Sterling Iron Mine at Antwerp. Foliated, two-toned gray plates of bladed stilpnomelane are jauntily set in matrix. Stilpnomelane is an uncommon layered silicate, related to mica and chlorite group minerals and this is a very highly representative, old-time specimen. This old mine closed in 1910. Comes with an expertly handwritten, faded label from an older collection. The collection this came out of was a museum stash dating to prior to World War I.
