Unknown Owner
A grouping of double terminated crystals of what were once serandite, these now replaced by birnessite. The cluster is complete all around with no points of attachment and in great condition. Crystals of polylithionite, aegirine, and micro rhodochrosite are present. These are classic pseudomorph specimens for this famous Canadian locality.
