An exceptionally rich specimen of this rare thallium bearing mineral, hosting numerous bright crystals sprinkled on a matrix of matte gray sulfides and dark orpiment.
Most of the hutchinsonite specimens in collections were recovered from this locality in the 70's and 80's, though over the last 2-3 years I have seen examples from more recent workings. I obtained one lot a few months ago, then this one right after Tucson. The pieces from this second lot are much closer in appearance to the old time pieces.
Hutchinsonite is a sulfide of thallium, lead, and arsenic and is probably one of the few minerals containing thallium that you can actually find a decent specimen of.
