Description: This is the highest grade lode gold specimen to be found anywhere. Overall weight is 19.6 grams of which 15.46 grams* is raw natural gold. It measures 30 x 22 x 15 millimeters (1.8 x 0.86 x 0.59 inches) shot through with multiple native gold veins. Mined from a strike in the Strawberry Mountains of eastern Oregon, this ore is what the '49ers dreamed of and qualifies as true 'mother lode' material. It is truly rare to find a piece of this size and quality that escaped production milling, processing and smelting. The host 'Bull Quartz' (calc-silica) is sparsely stained red throughout the specimen from oxidized native iron. This could well be the centerpiece for any rock or mineral enthusiast collection or mounted as an incredible necklace piece. The Specific Gravity Test (used to calculate the gold content of gold nuggets that contain a mixture of gold and other materials) This nugget is gold mixed with quartz. Simply put, the formula is 3.1 x the weight (suspended) in water, minus 1.9 x the weight in air: Wet nugget weighs 17.0 grams x 3.1 = 52.7Dry nugget weighs 19.6 grams x 1.9 = 37.24 52.7 - 37.24 = 15.4631.1 = number of grams per troy ounce15.46 / 31.1 = 0.497 ozt
