Colorado Quartz Mine, Mariposa Co., California, USA

The Colorado Quartz-Mockingbird gold properties form a continuous vein system with irregularly distributed amounts of crystallized Gold appearing at structurally controlled points. In the past, attempts to quantify true production resulted in a complete lack of concordance. What is known is that at least one specimen from the Colorado Quartz portion of the vein has reportedly sold for around one million dollars: i.e. The "Dragon" currently in the Houston Museum of Natural Science. Although not as big as the Dragon, this well-crystallized example shows the same brilliance of luster and perfection of crystal form as that specimen. There are elongate crystals up to 11 mm in length and a flattened octahedron of similar dimension. Crystallization is equally good on both sides, as can be seen in the photos, so it is hard to decide which is "front" and which is "back." Luster is as good as it gets for Native Gold and the obvious high-karat nature of the piece is apparent in the rich coloration. There is a custom acrylic base.
Overall measurements: 3 x 1.75 x .25 inches (7.6 x 4.4 x .6 cm). Offered at no reserve.

Provenance: Collector's Edge [Hoppel Catalog # D0027]
