How to tell if gold nuggets are real?

To determine if gold nuggets are real, you can perform a few simple tests. First, check for a metallic luster and a weight that feels heavy for its size, as gold is denser than most other materials. You can also conduct a scratch test on a ceramic plate; real gold will leave a gold streak, while fake gold will leave a black mark. Lastly, use a magnet; real gold is not magnetic, so if the nugget is attracted to the magnet, it likely contains no gold.
