Top 5 Most Expensive Rarest Material on Earth

Do you know the most expensive and rarest material in the world, Not then check below, here we are presenting world’s Top 5 Expensive Rarest Material.


Cost per Gram- US $30,000
Tritium is a radioactive form of hydrogen and naturally occurring tritium is extremely rare on earth.

Uses of Tritium-
Tritium has multiple commercials uses including self-powered lighting(watches,map lights, knives, beatalights etc), Nuclear weapons(neutron initiator, boosting), Controlled nuclear fusion, analytical chemistry.

Diamond is the hardest natural material known on the earth. It has a hardness of 10 (hardest) on this scale.

Uses of Diamond-
Diamond is mostly used in making jewelries. The other uses of Diamond is cutting glass, polishing tools.



Cost per Gram– $27 Million

Californium is a radioactive metallic element first made in 1950 at the University of California Radiation Laboratory in Berkeley. Californium has the second-highest atomic mass of all the elements that have been produced in amounts large enough to see with the unaided eye.

Californium Uses-
Californium is fairly insoluble in water, but it adheres well to ordinary soil. So it is used to find water and petroleum layers in oil wells, as a portable neutron source for gold and silver prospecting for on-the-spot analysis.



Cost per Gram– $150 Million

Buckminsterfullerene (or Bucky ball) contains 60 carbon atoms (with nitrogen atoms housed in them). It has a cage-like fused-ring structure which resembles a football, made of twenty hexagons and twelve pentagons, with a carbon atom at each vertex of each polygon and a bond along each polygon edge.

Uses of Bucky Ball-
Bucky Ball has not been used in commercialized. In the medical field, elements such as helium (that can be detected in minute quantities) can be used as chemical tracers in impregnated buckyballs.



Cost per Gram-$62.5 trillion (estimated by NASA)

antimatter is material composed of antiparticles, which have the same mass as particles of ordinary matter but opposite charges. Making 1 gram of antimatter would require 25 million billion kilowatt-hours of energy.

Uses of Antimatter-
Antimatter has mainly used in Medical, Fuel & Weapons.
