    Mockingbird Mine, Whitlock, Whitlock District, Bagby-Mariposa-Mount Bullion-Whitlock District, Mariposa Co., California, USA
    This fine Gold specimen displays shining dodecahedral crystals of Gold rising from the interior of a colorless Quartz matrix. Some of the Quartz to one side is atypically euhedral and a small area of that is transparent: a very good indicator of its particular source. The specimen is quite heavy for its size, indicating that there is probably more gold hidden within the Quartz matrix, waiting to be revealed. The Mockingbird Mine, near Mariposa, California, shares a couple of things with its adjoining, more famous, neighbor: the Colorado Quartz Mine - a single, well defined structure that contains the odd, infrequent "pocket": a cavity sometimes containing crystals of metallic Gold of exceptional perfection. Rock between the pockets is uniformly barren of the precious metal, such that estimation of reserves and potential future production is virtually impossible. The other thing shared by both properties is the presence of euhedral and sometimes transparent Quartz crystals accompanying the crystalline Gold, such as in this specimen. The combination of transparent, well-formed Quartz and crystalline Gold is relatively rare for specimens of this metal. This extremely bright Gold specimen measures 2 3/4 inches high x 1 5/8 inches wide x 1 7/8 inches deep, is in pristine condition, and comes with a custom unlabeled base.
