Most of this specimen consists of buff-colored barylite in a rough, columnar mass with subordinate calcite (fluorescent red SW) and small stringers of brown serpentine. The distinct cleavage of barylite is well shown in this example. Formerly Harvard University specimen no. 89179, it was later sold by Jim Kaufman (Jim's Gems, Wayne, New Jersey) to John Kuzma and still later was acquired by Mark Leger.
