The most expensive substance or thing on the planet Earth
The prevailing belief among many people was that gold or diamonds are the most expensive thing on the planet, as they are the most popular and used, especially gold, but in fact, this is not true at all, as there are materials that are hundreds of times more expensive than the price of gold and diamonds. It is one of the rarest and most expensive substances on the planet, but it is the second most expensive substance on the surface of the earth after antimatter, which is the substance "Califonium".

The second most expensive thing on the planet is calyphonium
There are many expensive things in the world, and there are some things that are not subject to pricing, bearing the phrase "priceless", and in an interesting list of a number of very precious and expensive materials, we find a list of the most expensive materials in the world, including energy sources, precious metals and types of materials narcotic;
The reasons for the high prices of these materials are due to several things, foremost of which is the lack of supply of these materials around the world compared to the demand for them, or because of their scarcity or difficulty in their production, or even the prevention of their trade and circulation in many countries.
The most expensive material in the world or the most expensive thing on the planet:
Coming first is Antimatter

Antimatter is the most expensive thing on the planet
Antimatter is considered the most expensive thing or the most expensive substance on the planet due to the scarcity of the materials that make up antimatter and its imaginary cost. The formation of antimatter requires the interference of the positron, which costs about 25 billion dollars per gram, and antihydrogen, which costs about 62 trillion dollars per gram, returns The high cost of producing antimatter is due to the interference of positron and antihydrogen and their cost is very astronomical, and the production of very small quantities of antimatter requires very sophisticated equipment such as those of European research organizations. One of the most prominent and most famous uses of medical tomography.
In second place comes the substance "Californium".
Califonium is considered one of the most expensive things on the planet, and the price of one gram of this substance is $27 million. Cunningham and Asprey, working at the American Atomic Energy Authority, discovered element 252 in the periodic table called "calfonium". The two scientists were able to manufacture this source in special nuclear reactors in very small quantities.

Calfonium is the second most expensive substance on Earth
The element "calfonium 252" is one of the most accurate, richest and most expensive elements after antimatter, so that only 0.2 grams of it is produced annually, a small amount, but it has countless advantages and benefits.
The great advantage of these fine neutrons is that they contain the same properties of neutrons generated by the atomic reactor, so the gram of them is considered a very precise and small atomic reactor and its usefulness is indescribable compared to its cost, no matter how expensive it is compared to other conventional reactors, and Califonium is one of the most toxic substances.
The third most expensive and most expensive material on the planet is diamonds

Diamonds are the third most expensive substance on the planet
Diamonds are one of the most famous and precious metals, and it is the third most expensive thing in the world after antimatter and caliphonium. The price of a good diamond earring is about 55 thousand dollars. Diamonds are used in many industries, the most famous of which is the manufacture of jewelry and accessories. Diamonds are also used in the manufacture of giant excavator heads due to its great hardness.
Fourth place Tritium:
 The most expensive substance or thing on the planet Earth 9154
Tritium is the fourth most expensive thing in the world
Fourth, tritium is one of the most expensive materials on the planet and the most expensive. Tritium is a radioactive element used in extracting atomic energy. Tritium is used to launch and ignite the detonating sequence in a hydrogen bomb, while the price of one gram of tritium reaches 30 thousand US dollars.
Fifth place in the list that includes the most expensive things on the planet and the most expensive is the Taffy Stone
The most expensive substance or thing on the planet Earth 10134 
Taffeta stone is one of the most precious gemstones in the world and one of the most precious things on the planet
The taffia stone is considered one of the most expensive things in the world due to the scarcity of the stone. It is one of the precious stones and is used so far in rare and valuable ways as jewelry. The price of one gram of the taffia stone is about 20 thousand dollars, and there is another stone called the peat stone, which is also a very rare gemstone. Like the taffia stone, the price of one gram is approximately 9000 US dollars.
