Gold

Gold is one of the most valuable minerals. Gold doesn't  rust and it has a beautiful color. Gold is really soft. It can be mixed up with other things like iron pyrite aka fools gold.

When Olympic and other sports players get a gold medal they bite into it to see if its real gold. If its real gold you can see your tooth print. If its fake you can not see your tooth make and is really hard.
