Wow. This is the most amazing hoppered natural gold nugget that I have seen. The hoppering is formed by multiple parallel striations in the surface of the gold. The striations are formed into rare Crystalline Plate Gold. It was found by a gold prospector in Australia. It is clean and free from any host rock or mineralization qualifying it as the highest jewelry/investment grade. Plate gold is natural crystalline gold that is formed into a thin flat "plate", giving it a very large surface area for the weight. It is shaped like a very elegant swan. You rarely see such rare gold nuggets like this offered for sale, but my wife and I are retiring soon and we need to reduce our collection to keep our bills paid. It measures 3/4" (18 mm) long and the weight is 5.2 Grams (80.2 Grains). I only have a couple of plate gold nuggets left in my collection, and once they are gone that's it. Like all of our other raw gold nuggets and specimens, it comes with a certificate of authenticity.
