Formula
Ag (RRUFF)
Locality
Cobalt-Gowganda dist., Ontario, Canada

A fascinating specimen which is sawed and polished to display the ore paragenesis and forms of the Silver crystals locked inside agatized or Chalcedony matrix. The Cooke label indicates Nephrite, but this is doubtful. The Silver appears much like seaweed and has a green tarnish perhaps from a little nickel from the Smaltite.
