A REALLY HEFTY nugget of solid, pure antimony from a classic old US locale. These turn up in museum collections, this one in fact being an exchange out of a major old collection assembled in the late 1800s and early 1900s (T.H. Cole). It is REALLY hefty - shockingly so, in your hand, at 869 grams. Although not for everybody's display collection, this is definitely something unusual, and interesting.
