A very strange Illinois specimen that is evidently an old specimen, said to have come from surface workigns near the mine and from a well-known Illinois collection. Deep purple cubes, some possibly pseudomorphosed (associated with a yellow mineral that turns out to be Smithsonite), occur on matrix. The largest of the lustrous, translucent, cubes is 1.5 cm across. With this mining district kaput, good to great specimens will become rarities. NOTE: FROM THE TOM WIESNER COLLECTION, NOT ZINN. got mixed into the update, though. NOTE: according to Ross Lillie, this weird find was a single boulder about two-three feet across with pockets inside. It was found in the Spar Mountain area with outcrops on the side of a hill. He assumes there where maybe a couple of dozen specimens. The find wasen't anything important in 1959 so that probly why there was no record.
