Small Cabinet, 5.5 x 3.8 x 2.6 cm
SOLD
From the find from about 7 years ago, this is a piece from the find at the Estano Orcko mine. This specimen features a few good-sized, relatively sharp, dark, lustrous, modified dodecahedra of Sphalerite associated with minor Pyrite on the back. The Sphalerite has a very slight unusual "peacock blue-green" patina which is actually a Bornite "wash" that is seen on practically every specimen from this find.
