Diltz Mine, Whitlock, Bear Valley, Mariposa Co., California, USA

A blocky, very robust, surprisingly hefty crystallized gold specimen from this classic old US locale. The mine is now long closed and specimens with this attribution turn up only in old collections. It is complete all around and has a beautiful patina. Mass is 37 grams, or 1.2 ounces of gold, here. From the collection of Hubert De Monmonier (1919-2007), donated by bequest to the University of Arizona Museum to add to their displays and to provide specimens for sale to establish an endowment fund for museum operations, in perpetuity.
