Gold is a very valuable metal, and we use it a lot in jewelry because it is shiny and pretty.

One of the reasons it works so well in jewelry is because it is the most malleable of all metal.
That means you can smash it with a hammer and it won't break into pieces, it will just flatten or change shape, kind of like a really hard piece of clay.

Gold also does not change when it is out in the air or when it gets wet, like the way that copper turns green unless it is polished all the time.

It is also a very good conductor of electricity, so it is used in computers and circuits a lot.

Because gold has so many uses and is so pretty, it has been used as money in the past.
People still will pay lots of money for gold no matter where in the world you are.
