Contrary to what the name might suggest, there's actually not that much gold in a gold medal. While the medal's design is different for every Olympics, it must adhere to guidelines set by the Olympic Charter.
One of those guidelines states that at least 6 grams of gold must be used in each gold medal.
This year's Olympic gold medal is comprised of 92.5 percent silver, just 1.34 percent gold, and the remainder 6.16 percent is made up of copper.
The gold and silver medals weigh 412 grams, while the bonze weighs 357 grams. Each medal is 85mm in diameter, and 8-10mm thick. These are the biggest and heaviest medals ever produced for the Summer Olympic Games.
