This unusual specimen is from a old collection we acquired some years back. It is shipped with it's original label. We really enjoyed this unusual specimen and it has certainly brought a lot of discussion to the table whenever we brought it out to show fellow mineral collectors. Packed shipping weight +/- 200gr.
