Gold has retained its value throughout history, partly due to the fact that it is indestructible.
As Visual Capitalist's Govind Bhutada details below, that means that virtually all the gold in the world that has been mined is still around in one form or another. Some of it may have turned into jewelry, while some might be sitting inside vaults as bullion. So, just how much gold have we mined, and how much of it is left beneath the ground?
This infographic from Kalo Gold visualizes all the gold in the world that’s above ground and the identified reserves that we have yet to mine.
Where is All the Gold?
The World Gold Council estimates that miners have historically extracted a total of 201,296 tonnes of gold, leaving another 53,000 tonnes left in identified underground reserves.
If all of the above-ground gold were stacked beside each other, the resulting cube would only measure 22 meters on each side, which is a testament to the metal’s rarity. But where exactly is all of this mined gold?
Nearly half of all the gold ever mined is held in the form of jewelry. India and China have been the largest markets for gold jewelry consumption, combining for more than 50% of global jewelry demand in 2020.

Investors across the globe buy gold because of its ability to deliver value, and when inflationary pressures are high, gold often acts as a flight to safety. Consequently, investment is one of gold’s biggest end-uses, with over 44,000 tonnes of gold held as bars, coins, or bullion for gold-backed exchange-traded funds (ETFs).
Besides investors, central banks are also among the biggest holders of gold. Unlike foreign currency reserves, equities, and debt-backed securities, gold’s value largely depends on supply and demand. Therefore, central banks often use gold to diversify their assets and hedge against fiat currency depreciation. Central banks’ gold holdings account for almost one-fifth of all above-ground gold; as of 2021, official holdings exceed 35,000 tonnes.
Although gold is widely coveted as a precious metal, it also has various industrial uses, with applications in electronics, dentistry, and space. In fact, it’s estimated that a typical iPhone contains about 0.034 grams of gold, in addition to other precious metals. It is these industrial uses that account for 29,448 tonnes or roughly 15% of all above-ground gold.
Underground Gold Reserves
Before it turns into jewelry and bullion, gold goes through several stages in the supply chain, beginning with mineral exploration and mining of underground reserves. As of 2020, the world had 53,000 tonnes of gold in identified reserves. Here’s where all this gold lies:
Given their availability of reserves, it’s no surprise that Australia, Russia, U.S., and Peru are among the world’s largest gold producers, with only China having produced more in 2020. These reserves not only help determine current production but can also provide an idea of where gold mining could occur in the future.
In 2020, miners produced just over 3,000 tonnes of gold, and at this rate, underground reserves will last less than 18 years without new discoveries. However, it’s important to note that reserves can change and grow as explorers find gold in different parts of the world.
A Golden Future
Gold has been around for thousands of years, and it will likely remain that way in the future.
With rising concerns over the growth in money supply and inflation, gold will continue to deliver value and protect investors in times of volatility while preserving wealth for the long term.
