UNIQUE... A very unusual crystalline Gold specimen due to its location. Found several years ago at the Pittsburg Mine in the Lewis Mining District. Gold occurs in a spider web-like manner, as fracture filling, and the Gold has an irridescent...coppery color. Totally untouched with any chemicals. A specific  gravity determination indicates 5 Grams of Gold. Housed in a 2" X 2" perky box.
