This is a lovely and delicate Silver very reminiscent of the fine silvers from Batopilas, Mexico. The Silver crystals are in the classic herringbone pattern often associated with spinel twinning, and they have a fine luster and patina. Even without the added locality value, this is certainly a desirable and distinctive specimen. For a thumbnail Arizona silver, though, and for this mine in particular, it is both elegant and significant for its aesthetics and size as a full thumbnail. I have actually seen much larger specimens, some prices at not more than 4-5 multiples of this, but unfailingly they were less elegant and anyways, wouldnt make for competition-quality aesthetics - whereas THIS thumbnail does just that and would add a lot to any thumbnail or Arizona collection, I feel.
