This super nice Jewelry/Investment Grade Natural Gold Nugget was found by a gold prospector in Australia using a metal detector. Jewelry/investment grade nuggets are the highest grade you can buy, and that is all I sell, only the very best. This gorgeous natural gold nugget weighs 5.0 Grams, (77.1 Grains), and it measures over 3/4" (20 mm) long. The color is a gorgeous buttery gold color due to the high purity. The purity is estimated at 94% to 98% pure gold, making it among the purest natural gold nuggets in the world. This is a really beautiful super clean natural raw gold specimen.
