This awesome natural Australian Gold Nugget weighs in at a hefty 10.6 Grams (163.5 Grains). This is one of my favorite nuggets in this category because it has such a large surface area for the weight, and the color and shape are outstanding. Gold nuggets like this one from Western Australia are some of the purest in the world. The gold in this incredible natural gold specimen is 92% to 98% pure (22KT to 23KT). Holding a hefty natural gold nugget like this in your hand is incredible. This nugget is 1.25" (31 mm) long. A truly awesome Australian Natural Gold Nugget!
