Scratch test Gold is a very soft element, so scratching it will leave marks. Use a knife to try and scratch the surface of your rock. If it's gold, you'll see scratches. Pyrite will be too hard to be affected, and mica will flake off when scratched. If you don't have a knife handy, scratch gold with a piece of copper (like a penny).
