All the Gold Ever Mined
About 205,000 tonnes, enough to fit in three Olympic pools/Collective & Conceptual
The World Gold Council estimates that approximately 204,000-208,000 tonnes of gold have been mined throughout all of human history. Because gold is virtually indestructible (it does not corrode or rust), nearly all of it is still around in some form: jewelry, bars, coins, electronics, and central bank reserves. If you melted it all into a single cube, each side would be about 22 meters long, which means all the gold ever extracted from the Earth would fit comfortably under the Eiffel Tower.
Measurements
At gold's density of 19,300 kg/m³; a cube ~22 m per side
All gold ever mined formed into a cube; fits under the Eiffel Tower
~3,100 tonnes mined per year as of 2023
~16 quintillion kg; enough to coat the Earth's surface 0.5 m deep
