Watch List notes:

Natural gold-in-quartz specimen, 316.7 grams, from the Sixteen-to-One Mine in Sierra County, California. Roughly 2" cube. Very rare and beautiful natural crystal matrix (the kind of thing usually crushed at the mine) with sharp, flaky gold protruding from a cloud of opaque, white quartz, nice size and shape (fits in your hand). As explained in the accompanying letter of provenance, the gold in this specimen is "extraordinarily brilliant" due to an unusual 15% silver / 85% gold ratio. Pedigreed to the collection of William Ghidotti, formerly on display at the Wells Fargo Bank in Reno, Nevada.

Estimate: $7000 - 10000
