I don't know if the specimen is waterworn, and I can't explain the natural smooth surface. But is an unusual specimen, heavy and rare. It is one of the largest arsenic specimens I have seen come across my desk. Quite unique! There is a note on one of the older labels stating "extra good specimen, from my own collection". I assume the recipient was Bill Roberts, but I am not sure who made that statement, but I am sure is is true, even today.

This is a great representative specimen from one of the largest gold mines in the world, the Homestake Gold mine. It is not in operation any longer. Gold occured in Cummingtonite schist with Arsenopyrite. There is no Gold on this specimen, however, with careful splitting, you may find some. The Arsenopyrite takes on some crystal forms as seen, generally they are crude and reach 7mm.
