This is a really incredible gold nugget from Costa Rica. It has a teardrop shape, very unusual and perfect for soldering on a gold bail and making it into a gorgeous gold nugget pendant. This is one of several hand selected gold nuggets from Costa Rica that I acquired from a contact who buys them directly from prospectors in Costa Rica. This beauty has an amazing buttery gold color due to the very high purity at 92% to 98% pure gold. The weight of this high quality investment/jewelry grade gold nugget is 10.1 Grams (155.8 Grains). at 1.25" (27 mm) long it has a lot of surface area for the weight.
