Earth is filled with precious metals that have been used to build civilizations, create art and jewelry, and even traded as currency. From gold to platinum to osmium, the rarest of these metals are highly sought after and incredibly valuable. But what is the rarest metal on earth?
The answer may surprise you. While popular belief is that gold is the rarest metal, this is actually not true. The rarest stable metal on earth is tantalum, a hard, grayish-blue metal. It is found in trace amounts in the Earth’s crust and is used in a variety of industrial applications, from electronics to nuclear reactors.
But even rarer than tantalum is an unstable element called francium. This element has a half-life of only 22 minutes, making it far too unstable to be used in any practical way. As a result, it remains one of the rarest elements on earth.
In terms of abundance in the Earth’s crust, there are five metals that are the rarest. These include gold, platinum, osmium, iridium, and palladium. All of these metals are extremely rare and valuable, and are often used in high-end jewelry and in other applications that require a strong and durable metal.
Osmium, rhodium, and iridium are the three most expensive metals, with average concentrations of 0.0001, 0.0002, and 0.0003 parts per million by weight, respectively. They are used in a variety of applications, from aircraft engines to medical devices, and are among the most valuable substances on earth.
The second rarest metal on earth is two of the world’s rarest metals, rhodium and osmium. These metals are estimated to be three parts per billion and 0.6 parts per billion in the universe, respectively.
So while gold is not the rarest metal on earth, it is definitely one of the most valuable and highly sought after. The rarest metal on earth is actually francium, with its 22-minute half-life, and the five rarest metals found in the Earth’s crust are gold, platinum, osmium, iridium, and palladium. Osmium, rhodium, and iridium are the three most expensive metals, and the second rarest metal on earth is rhodium and osmium.
What is Earth’s rarest metal?
The rarest metal on Earth is actually francium, but because of its short half-life of 22 minutes, it has no practical use. The rarest stable metal is tantalum.

Which is the rarest metal on earth?
Metals are incredibly useful materials, with a wide range of properties and applications. Depending on which criteria you use, there are a few contenders for the title of rarest metal on earth.
Rarest Natural Metals
If you measure the rarity of a metal by its abundance in the Earth’s crust, then the rarest naturally occurring metal is francium. This element is so rare that there is less than 1 ounce of it in the entire world at any given time. Other rare metals include rhodium, which is estimated to be three parts per billion in the universe, and osmium, which is estimated to be about 0.6 parts per billion in the universe. By comparison, aluminum and iron make up 8.1 percent and 5 percent of the Earth’s crust, respectively.
Rarest Man-Made Metals
Some man-made metals are even rarer than naturally occurring metals, as they barely exist at all. These highly radioactive elements have incredibly short half-lives, so they’re not found in nature. The four rarest man-made metals are flerovium, oganesson, moscovium and livermorium, which have half-lives of 2.1 seconds, 0.9 of a second, 0.09 of a second and 0.06 of a second, respectively. Perhaps the rarest of them all is tennessine, as it has never been recorded to have a half-life.
Uses of Rare Metals
The rarity of certain metals can make them incredibly valuable and sought after. For example, rhodium is used in catalytic converters, which reduce the amount of harmful emissions from motor vehicles. Osmium is also used to make hard, corrosion-resistant alloys that are used in applications such as fountain pen tips. Man-made metals are used in research and development or in special applications, such as spacecraft or nuclear reactors.
In terms of abundance in the Earth’s crust, the rarest metal is francium, as there’s less than 1 ounce in the world at any given time. However, you could describe many man-made metals as being even rarer because they barely exist at all. The strength, high melting point, and thermal and electrical conductivity of metals make them incredibly useful materials with a wide range of applications.
What is the rarest element metal on earth?
When it comes to the rarest elements on Earth, the discussion often turns to rare earth elements.

These metals are different from Rare Earth Elements, which aren’t actually rare in terms of abundance, but are rarely found in concentrated ore deposits. Most of us have heard of gold and platinum, but the other seven are truly rare. What are they, where are they found, and why do they matter? Essentially, the heavy rare earths are much less abundant than the light rare earths, and so the heavy ones sell for much higher prices. The value of an ore is thus determined largely by the proportion of heavy rare earths found within it. Monazite was the primary mineral mined to produce rare earth elements from the 1890s until the 1950s.
Although the rare earth metals mentioned above are among the rarest elements on Earth, they are still relatively abundant compared to other elements such as astatine and francium, which are found in only trace amounts in nature. The rare earth metals are important for many industrial and technological applications, and understanding their abundance and distribution is an important part of understanding the Earth’s crust.
What is the rarest metal known to man?

In terms of abundance in the Earth’s crust, the rarest metal is francium, as there’s less than 1 ounce in the world at any given time. However, you could describe many man-made metals as being even rarer because they barely exist at all.
Man-Made Metals
Man-made metals are created in a laboratory setting, and many of them are highly unstable. The highly radioactive man-made metals flerovium, oganesson, moscovium and livermorium have half-lives of 2.1 seconds, 0.9 of a second, 0.09 of a second and 0.06 of a second, respectively. This means that they exist for a very short period of time before they decay into other elements. Perhaps the rarest man-made metal is tennessine because no half-life has ever been recorded.
The Strength of Metals
The strength, high melting point, and thermal and electrical conductivity of metals account for their wide range of applications. For example, iron and aluminum are used in construction and infrastructure, while gold and silver are used in jewelry and electronics. Other metals, such as titanium and tungsten, are used in medical implants and other specialized applications.
