Tiny botryoids and smatterings of almost forest-green Zaratite cover much of the display surface of this piece from the Wood's Chrome Mine in Pennsylvania. Zaratite is a rare nickel carbonate hydrate found as a secondary alteration product of ores containing nickel. This is a rich locality example of this rare species with bright green, micro-botryoids coating the main fracture surface along with other surfaces on the piece of chromite ore. The Wood's Chrome Mine is a historically significant U.S. locality and was operated from 1828 to 1881 and produced not only the best U.S. Brucite specimens, but also the best U.S. specimens of Zaratite.
