A fine specimen which shows much better in-hand than on the screen. Calcite crowns to top of this specimen with 5-8mm colorless crystals. The back side is covered with the same. The matrix is of large framboidal, brassy colored Marcasite crystals. It's a very nice specimen with an accurate locality - the Elmo mine, which was personally collected by RJ Waidler in 1970.
