An attractive rolling plate of botryoidal native arsenic, with a big bubbly growth atop. Minor cracking in some botryoids, as in some other specimens, but the cracks do not go through the piece. There is also some unusual greenish mineralization on the bottom. From a large but highly unusual find of pure arsenic in this historic mine, found in summer of 2013. Although we have seen many specimens from this mine, including fine orpiment, I had not previously seen pure native arsenic. Moreover, this is of the quality to rival the old German specimens of native arsenic, which have traditionally sold for far higher prices.
