It comes as tensions between the US and NATO over Greenland have added to growing concerns about financial and geopolitical uncertainty. BBC reported.
US President Donald Trump's trade policies have also worried markets. On Saturday he threatened to impose a 100% tariff on Canada if it strikes a trade deal with China.
Gold and other precious metals are seen as so-called safe-haven assets that investors buy in times of uncertainty. On Friday, silver topped $100 an ounce for the first time, building on its almost 150% rise last year.
Demand for precious metals has also been driven by a range of other factors including higher-than-usual inflation, the weak US dollar, buying by central banks around the world and as the US Federal Reserve is expected to cut interest rates again this year.
Wars in Ukraine and Gaza, as well as Washington seizing Venezuelan President Nicolás Maduro, have also helped push up the price of gold.
One of the biggest appeals of gold is its relative scarcity. Only around 216,265 tonnes of the metal have ever been mined, according to the World Gold Council trade association.
That's enough to fill between three to four Olympic-sized swimming pools. The majority of that was only extracted from the earth since 1950, as mining technology advanced and new deposits were discovered.
The US Geological Survey estimates that another 64,000 tonnes of gold can still be mined from underground reserves, although the supply of the metal is predicted to plateau in the coming years.
"When you own gold, it's not attached to the debt of somebody else like a bond is or an equity where the performance of a company will drive performance," said Nicholas Frappell, global head of institutional markets at ABC Refinery,
"It's a really good diversifier in a very uncertain world," he added.
