How must the Olympic medals be made?
Each Olympic medal must be at least 68mm across and 3mm thick. The gold and silver medals must contain at least 92.5% silver, and at least 6 grams of 24-carat gold must coat each gold medal.
Bronze medals contain copper, zinc, tin and a very small amount of silver.

Design Features
Since 1928, the front side of every medal has featured a picture of Nike, the Greek goddess of victory. A new design was created for the 2004 Games, featuring the Greek Stadium and a new image of Nike. Based on a statue carved in 421 BC which was kept in the Temple of Zeus in Olympia, the new image shows Nike flying into the stadium as if to crown the winners with a wreath.

Reverse Side
The reverse side of every medal is unique to each Olympic Games and is designed by the host city. The medal for the Beijing 2008 Olympic Games has been inlaid with a jade disk, inspired by an ancient Chinese piece called "Bi". Jade has an important place in Chinese culture as it represents beauty and excellence in all things. The medal hook is inspired by the dragon which is a symbol of strength and power.
