but the cost of making anti-hydrogen atoms is very expensive. It is said that one gram can bankrupt a small country, and it takes trillions of dollars to produce every gram of antimatter.

2.Californium. **: $27 million per gram. Although californium is synthesized and came out in 1950, it is currently the most expensive chemical element.

There are currently only two companies in the United States that can produce it, and now it is worth $27 million per gram, which is 20 times that of **.

3.Drosilicate.

**: $300,000 per gram. It is said that there are only a few hundred stones in the world.

It was only discovered in 51 years and was only found in two states of Myanmar. It is currently one of the least precious gemstones, so its ** is as high as $300,000 per gram, ranking it as one of the top 10 most expensive rare items in the world.

5.Tritium. **：

$30,000 per gram. Tritium is the fuel for hydrogen fusion, and it is very difficult to obtain and can almost always be done by artificial synthesis. However, it costs $30,000 per gram to make, making it one of the top 10 most expensive rare items in the world.

6.Beryllium magnesia.

7.Plutonium. **: $4,000. It is a silvery-white radioactive metal. Although it can cause cancer, it can act as a nucleus**.

Research raw material for fission, worth $4,000 per gram.

8.Horns. **: $110 per gram. Rhino horn.

It is also one of the 10 most expensive rare items in the world.

Hello, the most expensive rare items in the world are: **, Tanzanite, Plutonium, Beryllium Magnesium Crystal, Tritium, Siboronite Calcium Stone, Californium, Transhydroatoms, Taaffeite and Diamonds. The most expensive of them is the anti-hydrogen atom, which is 6.5 billion dollars per gram, and it can be said that small countries simply do not have the capacity.

Californium, diamonds. Anti-hydrogen atoms, plutonium, borosiliconite, beryllium magnesium crystal, rhodium, platinum, tritium, rhino horn are all very rare, and they are all calculated in grams. Each gram is trillions of dollars.

The most expensive rarities are anti-hydrogen atoms and borosilicate; One gram could reach around $1 billion.
