At 12.5 Grams (192.8 Grains) this incredible gold nugget from Costa Rica is huge. The color is amazing, because of the high purity (92% to 98% pure gold) it has a gorgeous buttery gold color and a smooth surface. It is definitely a hand selected investment/jewelry grade natural gold nugget. My contact buys these nuggets directly from the prospectors in Costa Rica and they are not often offered for sale. I buy only the highest quality gold specimens from him and the rest go to the refiner to melt. This amzing gold nugget would make a great investment and a nice addition to your collection.
