This specimen features wildly elongated crystals showing the cubic form in some places, and dodecahedral crystals elsewhere. I would swear the central stalk is a single large spinel twin except that it seems too robust, so it is perhaps an elongated copper crystal of "normal" habit, stretched beyond expectation. This was probably found during the heyday here in 1844-1890 according to the Seaman Museum folks. In any case, a fanciful and sculptural specimen chosen for the collection for its obvious display qualities. Neal Yedlin traded this from Lou Moyd of the Royal Ontario Musuem, in the 1960s or 70s, I am told. Comes with custom lucite display base.
