Gold is such a wonderful and diverse metal, it's not just used for some of the most incredible jewellery but is actually reserved by countries all over the world. Why? Gold is reserved as a sort of back up, should a country be down on money (essentially). It's like a long term investment, so if the price of gold rises they can trade some of their gold for cold hard cash. Below is an infographic that looks as a handful of countries, known for their gold reserves, showing how much they actually have with an interesting fact or two about gold itself. It is interactive so have a look and click on the countries. Who do you think has the most gold?
