Totally covering a thin crust of matrix is a bubbly surface of drusy, spherical, lustrous, deep green pseudomalachite. Perched on the pseudomalachite are lustrous, green-black crystals of libethenite, to 3 mm across. Ex Bill Pinch collection. He obtained it from mine engineer Warren Taylor. A rare piece, both for the locale and the combination of species, this is the only one I have seen for sale until now. I am told these came out in the 1980s.
