A total of 165,000 tonnes of gold have been mined in human history, as of
2009.[2] This is roughly equivalent to 5.3 billion troy ounces or, in terms
of volume, about 8500 m3, or a cube 20.4 m on a side. The world consumption
of new gold produced is about 50% in jewelry, 40% in investments, and 10% in
industry.[3]
