Gold is seen as a safe investment that won't lose value in difficult times. But the glimmer of gold is even brighter for those who discover the precious metal themselves. Click or scroll through to read the stories behind the biggest single gold finds of all time.

A number of eye-popping nuggets were discovered during Brazil's Serra Pelada Gold Rush in the early 1980s. Notorious for its high levels of crime, the Amazonian gold rush also caused considerable environmental damage. The fifth biggest nugget found, the Canaã 5 weighs 646 ounces, and is on display at the Banco Central Museum in Brasília. Pictured is the site of the now-closed Serra Pelada gold mine.

America's third largest true gold nugget was found at Magalia, California in 1859. Weighing in at a hefty 711 ounces, or 54 troy pounds, the hunk of gold is variously known as the Dogtown, Willard or Magalia nugget. A party was held following its discovery, and the nugget was melted down not long after.

The vast majority of supersized gold nuggets have been discovered in Australia. This shiny piece of the precious metal was discovered by Chinese prospector Loo Ching in April 1871 at a depth of just under 13 feet at Catto’s Paddock, Berlin (now Rheola) in the Australian state of Victoria. The sizable nugget was melted down but a replica (pictured) forms part of the Mineralogy Collections at Museum Victoria.

Discovered in either 1857 or 1858 by Nicholas McAvoy and Walter Palmer, the McEvoy (which is curiously spelled with an 'E' rather than an 'A') Nuggets were, like the Kow Tow Nugget, unearthed in the gold-rich Rheola locality in Victoria. No longer in existence, they weighed 810 ounces, 805 ounces and 782 ounces respectively.

A far more recent discovery, the stunning Normandy Nugget was found in a dry creek bed in Kalgoorlie, Western Australia in 1995. The property of the Newmont Mining Corporation, the sparkling hunk of gold, which weighs 899 ounces, is currently on display at the Perth Mint.

Staying in Australia, the Poseidon Nugget was found at the eponymous goldfield in the mining town of Tarnagulla, Victoria in December 1906. Weighing a total of 953 ounces, according to contemporary news reports (the weight on the image is incorrect), the find, just before Christmas, inspired a festive gold rush.

The spectacular Hand of Faith Nugget is the largest discovered using a metal detector. On display at the Golden Nugget Casino Hotel in Lake Charles, Louisiana, the dazzling rock was found by Kevin Hillier near Kingower in Victoria, Australia in September 1980, a mere 12 inches below the ground. It was reportedly sold at the time for over $1 million, which is $3.1 million in today's money.

Another splendid nugget that was discovered in the gold-rich Rheola locality in Victoria, Australia, the Viscountess Canterbury was found at John's Paddock, Berlin in October 1870.

One of the largest nuggets discovered during Australia's Victorian Gold Rush, which established 'Marvellous' Melbourne as the country's second city, the 1,099-ounce Canadian 3 was found in January 1863 at Canadian Gully, Ballarat.

Named after a popular gold commissioner rather than the aquatic bird, the Heron Nugget was found near Old Golden Point in Fryer's Creek at the Mount Alexander goldfield (pictured) in March 1855 during the Victorian Gold Rush.

The largest gold nugget discovered in America was suitably named the Monumental. Weighing in at between 1,648 ounces and 1,696 ounces, it was discovered by five prospectors in August 1869 in the Monumental Claim in Sierra County, California. The find was sold to wealthy San Francisco hotel owner Robert B. Woodward not long after for a bargain $13,000, around $240,000 in today's money.

The Blanche Barkly was found by a team led by Scottish prospector Sam Napier in August 1857 at Kingower, Victoria.

The largest surviving true gold nugget on the planet, the Canaã is the biggest lump of gold extracted during Brazil's Serra Pelada Gold Rush in the early 1980s. Valued at $2.6 million, it is on display to the general public at the Banco Central Museum in Brasília, along with its smaller counterparts.

Not a true nugget as such due to its impure content, this enormous gold-encrusted rock was discovered in September 2018 at RNC Minerals' Beta Hunt mine near Kambalda, Western Australia. Valued at $2 million, the impressive slab reportedly contains 1,600 ounces of pure gold.

The biggest nugget discovered in gold-rich Ballarat, Australia, the Welcome Nugget was unearthed by a group of miners from Cornwall, England in June 1858. It was sold for £10,500, which is $1.7 million in today's money. Like the Blanche Barkly Nugget, the huge lump of gold (the photo shows a replica) was exhibited at London's Crystal Palace, and eventually bought by the Royal Mint and melted down into sovereign coins.

Miners working for RNC Minerals unearthed an even larger gold-encrusted rock at the Beta Hunt mine in Western Australia back in September 2018. This eye-opener weighs in at a back-breaking 3,351 ounces and is said to contain around 2,400 ounces of pure gold valued at $3 million.

The magnificent Welcome Stranger, the granddaddy of all true gold nuggets, was found by English prospectors John Deason and Richard Oates in February 1869 at Moliagul in Victoria, Australia. Weighing in at a jaw-dropping 3,524 ounces, the monster nugget was broken up into three pieces that were later melted down. It would be worth at least $3 million if still intact today.

While the Welcome Stranger is the largest gold nugget ever found, the biggest single gold specimen discovered on the planet is the Holtermann 'Nugget'.
