10. Silver

Largest Producer: Mexico

Price Tag: $0.80 per gram

Probably the most common meal on earth, Silver has a price tag of $0/80 per gram.

A white, soft, lustrous transition metal, silver’s symbol is Ag, and atomic number is 47.

Besides, silver is the highest electrical, thermal conductor and reflector than the rest of the metals found on earth.

In addition, Silver is highly ductile in nature with a lower covalent bond.

Moreover, Ontario’s first geologist, Miller Willet Green, discovered silver deposits in Northern Ontario in 1902.

Whereas most of the silvers are extracted as a by-product of gold, lead, copper, and zinc refining.

Also, silver can be easily found in its pure elemental form in the earth’s crust as an alloy with gold, and other precious minerals, metals.

Especially, everyone uses silver as a bullion coin and for the manufacturing of solar panels, jewelry, utensils, medical instruments, etc.

9. Indium

Largest Producer: China Price Tag: $1- $5/gm

Indium is a silvery-white chemical element and a post-transition metal that creates 0.21 parts per million of Earth’s crust.

Similarly, the symbol of Indium is In, and it falls under the atomic number 49.

At first, two genius German chemists, Ferdinand Reich and Hieronymous Theodor Ritcher, discovered Indium in 1836 through the use of an optical spectrometer.

Later, they named the chemical component Indium due to the appearance of an indigo blue line in its spectrum.

Also, Indium is the softest metal on earth which is not an alkali metal.

Whereas, Indium dissolves more easily than other metals in liquid mercury and plays a huge role as a reducing agent during the oxidization process.

Especially, semiconductor industries use Indium to produce goods like alloys, solders, indium tin oxide, widely used in TV screens, mobile screens, and solar panels.

Thus, a pure Indium costs around $1- $5 per gram, making it the world’s tenth most expensive metal.

8. Iridium

Largest Producer: South Africa

Iridium is the eighth-most expensive metal in the world, worth $18.34/gram.

Besides, the second-densest metal on earth appears brittle with a silvery-white tint.

Especially found abundantly in meteorites than at the earth’s crust, iridium is the most corrosion-resistant metal.

At a normal room temperature, iridium forms iridium disulfide when reacted with sulfur.

Whereas neither acids nor aqua regia can harm iridium.

An English chemist, Smithson Tennant, discovered iridium in 1803.

Similarly, Tennant named the precious metal after the Greek goddess Iris as its striking salt resembled the colors of the rainbow.

It can be obtained as a by-product from nickel refining.

Moreover, South Africa is the largest producer of the metal, trading it to several countries for creating watches, compasses, and varieties of automobiles.

7. Osmium

On the seventh rank of the ten most expensive metals in the world is Osmium, with a price tag of $31.1 per gram.

The rarest earth metal with hard, dense, brittle, bluish-grayish tint, osmium’s symbol is Os, and atomic number is 76.

Especially, osmium can be found in a crystal form and gives a strong scent of osmium tetroxide.

Though osmium shows less reaction and toxicity than other metals, it is a great oxidizer.

Besides, the earth only preserves about 0.6 parts per billion of osmium, mainly obtained as a by-product through nickel refining.

British chemist Smithson Tennant discovered osmium in the left residue when aqua regia dissolved crude platinum in 1803.

In addition, osmium is twice denser than Lead.

Thus, several industries use it to produce fountain pen tips, hardest alloys, instrument pivots, electrical contacts, chemical catalysts, and needles, etc.

6. Rhenium

Largest Producer: Chile

Price Tag: $41.47 per gram

On the sixth rank of 10 most expensive metals in the world is Rhenium, with a price of $41.47 per gram.

Besides, the rarest chemical metal in the earth’s crust, rhenium’s symbol is Re, and atomic number is 75.

Similarly, the metal appears silvery gray, heavy with the third-highest boiling and melting point than the other stable elements at 5869K.

Whereas, when heated, Rhenium can be turned into a coil form.

At first, three German chemists, Walter Noddack, Ida Tacke, and Otto Berge, discovered rhenium through X-ray spectroscopy in 1925.

Also, rhenium was the last stable element to be discovered after hafnium.

In addition, the scientists named rhenium after the Rhine river in Europe.

Moreover, one can obtain Rhenium as a by-product of molybdenum processing.

Several industries use Rhenium to produce jet engines, tungsten, molybdenum-based alloys, lead-free high octane gasoline, and filaments in spectrographs, etc.

5. Gold

Largest Producer: China

Price Tag: $57.45 per gram

Gold is the world’s fifth most expensive metal, worth $57.45 per gram.

The world’s most familiar precious metal appears bright yellow, dense, soft, malleable, and ductile in its purest form.

Also, the relatively rare metal in the earth shows the least reaction as a chemical element.

Egyptian goldsmiths smelted down the gold at around 3600 B.C.

Moreover, it can be obtained mostly in its pure elemental native form, like in nuggets or grains in rock and alluvial deposits.

Likewise, China is the top producer of gold, producing 440 tones of gold annually.

Especially, we use golds as fine jewelry, wedding rings, in arts, gold medals, awards, and as a status of wealth.

4. Palladium
