This is a beautiful specimen of MANGANITE from the Caland Pit, Antitopan, Hutchinson Township, Ontario, Canada - an extinct open pit mine. Manganite from this mine is arguably the finest available outside of the Ilfeld locale in the Hartz Mountains of Germany . We picked this piece up at the East Coast Gem, Rock & Mineral Show from a Canadian wholesale dealer who acquired it as part of an old collection.
