This is a super nice Australian Natural Gold Nugget from Western Australia. The gold is very pure at 92% to 98% pure (22KT to 23KT) giving it gorgeous color. It weighs 1.56 Grams (24.2 Grains) and it is 7/16" (11 mm) long. It has fantastic color and texture. It is a jewelry/investment grade gold nugget, clean and free from any host rock or mineralization. I hand selected all my gold nuggets from the collections of multiple gold prospectors. That's why I have so many super nice high quality raw gold nugget specimens. As with all our gold nuggets, it comes with a certificate of authenticity.
