Fun Fact of the day: An adult human body weighing 70 kg contains about 0.2 milligrams of gold. It's been found that the element plays an important health function, helping to maintain our joints, as well as facilitating the transmittal of electrical signals throughout the body.
Toenails of the human body contains the most gold . Was this answer helpful?
There are several precious metals in the human body, including gold, silver, platinum, and palladium. Each of us has up to 0.2 milligrams of gold in our body, and most of it is found in the blood.
For faeces samples, the median platinum concentration was 10.5 μg kg−1 FW. The excretion of platinum over a 4-day period was measured in one adult male. Urinary excretion of platinum was between 0.76 and 1.07 μg Pt day−1 and in faeces it was between 0.61 and 0.73 μg Pt day−1.

1. RHODIUM: TOP MOST VALUABLE METAL. Rhodium is the most valuable metal and exists within the platinum group of metals. It is used in jewelry for a final finish on white gold jewelry.
The rarest stable metal is tantalum. The rarest metal on earth is actually francium, but because this unstable element has a half life of a mere 22 minutes, it has no practical use.
Calcium is the most abundant metal in the human body, at around 1.4% by mass. Arguably its most well-known function is in the formation of bones and teeth and lack of calcium in the diet can lead to a variety of degenerative conditions.
About 244,000 metric tons of gold has been discovered to date (187,000 metric tons historically produced plus current underground reserves of 57,000 metric tons). Most of that gold has come from just three countries: China, Australia, and South Africa.
So we've estimated that within 4000m of the surface of Earth's crust there is 35 billion tons of gold. With a remaining 87 billion under the ocean.
1 karat gold weighs 1 gram. The price per milligram of gold depends on the market conditions and the type of gold being bought. Generally, the price of gold per milligram ranges from approximately $0.18 to $0.90 USD.
The United States holds the largest stockpile of gold reserves in the world by a considerable margin. In fact, the U.S. government has almost as many reserves as the next three largest gold-holding countries combined (Germany, Italy, and France). Russia rounds out the top five.
Platinum is 30 times more rare than gold. If all the platinum ever mined were melted and poured into an Olympic-sized pool, the platinum would barely reach your ankles.
PGMs are among the rarest metals on Earth. Platinum, palladium, and rhodium are rarer than gold. Iridium, osmium and ruthenium are even rarer than the other three.
Platinum in the Earth's crust originates from ultra-mafic igneous rocks. It can therefore be associated with rocks like chromite and olivine. In nature, pure platinum is unknown and well formed crystals are very rare.
China. Unsurprisingly, China has the highest reserves of rare earth minerals at 44 million MT. The country was also the world's leading rare earths producer in 2022 by a long shot, putting out 210,000 MT. Despite its top position, China remains focused on ensuring that its reserves remain elevated.
Because of its purity, 18k gold is also one of the most expensive types of gold available. If you're trying to buy jewelry on a budget, this isn't a realistic option.
For starters, gold is far more abundant in the earth's crust, making platinum rarer. Whilst 1,500 tons of gold are mined annually, only 160 tons of platinum are extracted.
If you were hoping make your fortune mining the sea, consider this: Gold in the ocean is so dilute that its concentration is very small. One study found there is only about one gram of gold for every 100 million metric tons of ocean water in the Atlantic and north Pacific.
While the role of gold in the physiological processes of the human body was unknown for many years, it has recently been determined that gold plays a role in both the health and maintenance of the joints, as well as being a key element in the transmittal of electrical signals throughout the body.
Gold was first discovered in California by James Marshall, who saw it in a river on his way to catch some boiling water. When he looked down, he saw gold flakes in the water. He soon went back and reported what he saw to his fellow miners.
