A lovely and very aesthetic little cleophane thumbnail from Spain consisting of a tiny crystal fragment of intense olive green sphalerite, with great gemines and a slightly dulled metallic luster, which features a main set of complex crystal faces on one side of the piece representing a section of the original crystal surface this piece broke off from that in this case luckily forms a very interesting composition. This piece was found and extracted from a fragment of the calcified pocket breccia often found at the bottom of geodes within the Aliva mine in the late 90's.
