This is a really gorgeous natural gold nugget from Western Australia. It weighs in at 1.9 Grams (29.3 Grains). It has a small inclusion of host rock on one side, which makes this a collectible grade gold nugget. I have been collecting these beauties for many years, picking out the very best nuggets from multiple gold prospectors collections. It is 7/16" (11 mm) long. Australian gold nuggets are highly valued by jewelers and collectors because of their high purity and gorgeous color. High quality nuggets like this one are approximately 92% to 98% pure (22kt to 23kt). It comes with a certificate of authenticity.
