Gold is considered one of the most expensive metals, and the most famous. Although gold prices are high and famous among the public, they are not expensive. There are more expensive metals, which require large amounts of money to meet demand. Minerals are considered commodities and measured by economic standards. We review 7 metals that are more expensive than Go, and their uses.
Antimatter:
It costs to get one gram of antimatter 6 billion dollars, to be the most expensive of all metals
There are only two institutions on earth that physicists have been able to obtain so far, LHS and Tevatron, and the areas where they can still be used are unknown.

2 - California:
The price of one kilogram of californium is $ 180 million. This element is 98 in the Mendeleev chemical table and is obtained in the laboratory by atomizing and detonating the atom's corium.

The material is used to study complex physical processes to find out the sources of this substance in supernova processes, where scientists are trying to help California know why supernova contains large amounts of gold.

Diamond:
Diamonds are the most precious metal among the famous minerals on the earth. The "Hopediament" is one of the most expensive types. The price of one gram is about 36.6 thousand dollars. The price depends on purity, color, polish and weight. Small, because they are naturally rare.
In the Mohs scale, where the hardness of metals is measured in the tenth place, it is formed in the ground under the influence of tremendous pressure. It is the hardest metal found naturally in large quantities. The industry that needs hardness uses 70% of the diamonds extracted annually. Tritium:

Tertium is a radioactive material, often used in the clock we see in the dark, and is used in hydrogen bombs. It is produced in nuclear laboratories, which is the heavier form of hydrogen.
Beta radiation from tritium is harmful in inhalation, or when it enters with food or drink, but it can not penetrate the human skin. Therefore, the user in the wrist watches is harmless, precious metal, the price of one gram is about three thousand dollars .

Plutonium:
Although the reputation of radioactive plutonium is poor, it has a high demand among scientists, as it is used as fuel in nuclear reactors and spacecraft that travel long distances. For example, the spacecraft "Fujir 1" "Their batteries contain plutonium that allows them to stay in motion until 2025.

6 - Red Beryl:
The value of one gram is about 2000 dollars and is rare metals is rarer than diamonds, as it has not been found in only two areas so far, one in Utah and the second in New Mexico, the United States.
The red beryl is used in the manufacture of ornaments and cosmetics. It belongs to a group of transparent colored stones, some of which are overlapping colors, and the most rare type is obtained from the color of iron atoms interfering with chromium, calcium and manganese.

Helium:
One gram costs $ 1000, a gas that is created by the decomposition of tritium radiation, and scientists are trying to use it to produce energy from the process of docking, the same process that takes place in the sun.
One of the most important difficulties facing scientists is the scarcity of this gas and the difficulty of its availability, but NASA has conducted a study proved the possibility of production on the moon, because of the collection of particles coming from the sun there.
I've put some information together so we can share ideas together and correct each other. Let's go to a good idea
