This Natural Australian Gold Nugget is my new favorite gold nugget. Check this out. It's shaped like a Polar Bear. How cool is that? These nuggets are so rare, and I have compiled what I think is the best collection of special shaped natural gold nuggets. This 4.11 Gram nugget is right up there with the finest distinct shapes that I have. When you look at the first photo you have to say, "Yep. That looks like a polar bear!" A fantastic addition to any gold nugget collection. It is 3/4" (19 mm) long and the wight of this incredible gold specimen is 63.4 Grains (4.11 Grams).
