strange, large Thenardite/Halite stalactite (rare Arizona locale)

Item Description

A fascinating, dramatic and rare large specimen from this ancient area, that was likely worked for salt as long as 2000 years ago (MINDAT). The Camp Verde Mine, a salt-clay-gypsum mine, was active in the 1920s and 30s. Many fine and unusual specimens have been collected since then and this is certainly one of them. This is a striking large hollow tube of knobby thenardite, Na-sulfate and halite, NaCl. We were told by an Arizona expert, that these were recovered in the early 1990s. RARE material in this size and quality! Value?? It seems unque in my experience.
