This beautiful natural gold nugget weighs 4.2 Grams (64.8 Grains). It is just under 3/4" (16 mm) long and it has gorgeous color and a real textured surface. Like all of my Australian gold nuggets, it is a jewelry/investment grade high quality natural gold nugget, found by a gold prospector using a metal detector in Western Australia. It has a little bit of quartz crystals attached to some of the crevices. Add it to your collection or put it away as an investment. either way you will enjoy this beautiful nugget. It comes with a certificate of authenticity.
