• ANTIMATTER ($100 Trillion per gram)

Antimatter, as the name suggests it is opposite to the normal matter (antiparticles). It has same mass as particles but have opposite charge. It is the one of the most expensive discoveries of 20th century. It is considered as for every particle we know has an antimatter companion that is virtually identical to itself.

As we know, an atom consists of nucleus, which in turn contains protons and neutrons. Electrons are negative charge that orbits around nucleus. On the other hand in antimatter, the electrical charge is reversed relative to matter, according to NASA. Anti-electrons (called positrons) behave like electrons but have a positive charge. Antiprotons, as the name implies, are protons with a negative charge.

The Antimatter are mainly used in the fields of medical, generate fuels for rocket and to create nuclear weapons.


  1. CALIFORNIUM-252 ($27 Million per gram)

Californium is a chemical element with the symbol Cf and the atomic number 98. It is consider as one of the most expensive element in the world. It has the second highest atomic mass.

The main behavior of this element is that it is a transuranic element, synthetic, radioactive. The 252 Cf is a strong emitter of neutrons and it is therefore extremely radioactive and harmful. The most of the isotopes of californium is generated by beta decay of 249 Bk and by bombarding the Berkelium with intense beams of neutrons in a nuclear reactor. The main application of this element is in nuclear science and is used in nuclear reactors.

  • DIAMOND ($65,000 per gram)

Diamond is an allotrope of carbon. It contains carbon, hardest natural substances in the world. Because of this diamond has a rigid lattice and hard as well. Diamond hardness depends on purity, crystalline perfection and orientation.

Pure diamond should transmit visible light and appear as a clear colorless crystal. Colors in diamond originate from lattice defects and impurities. The diamond crystal lattice is exceptionally strong and only atoms of nitrogen, boron and hydrogen can be introduced into diamond. The diamonds are primarily used in jewelry, and since it is hardest substance it is also used in industrial applications.

  1. TRITIUM ($30,000 per gram)

Tritium is an isotope of hydrogen; it contains one proton and two neutrons. It has an atomic weight of approximately 3 and has tripled the mass of the nucleus of ordinary hydrogen. It is usually produced in nuclear reactors as a byproduct of the irradiation of lithium.

Tritium was discovered on 1934 by physicists Ernest Rutherford, M.L. Oliphant, and Paul Harteck. Tritium is a radioactive species having a half-life of 12.32 years. It is mainly used in Self-powered lighting, nuclear weapons, in hydrogen bombs and in analytical chemistry.

  1. SCORPION VENOM ($10,000 per ounce)

Scorpions have two venom glands that produce venom used in hunting and self defense. Each scorpion has unique venom, so its toxicity may be different depending on the scorpions.

The venom is comprised of a group of complex molecules called a neurotoxin; these contain proteins consisting of 60-70 crossed linked amino acids. Some researches and studies say that this venom can be used to cure some medical diseases and can be used for treatments. These venoms can help to increase the chances of heart transplants being successful instead of failing. This type of treatment could be given as an injection to prevent cells from growing that would create complications around the heart. Certain studies say that this venom can cure Lupus and even Rheumatoid Arthritis. It is also used as pain killers. Thus this venom have different medical as well as other uses, so scorpion venom enters into this list of expensive materials in the world.
