Many people may only know about metals like Gold, Platinum as expensive materials. Some people may also be into diamonds and platinum. These are costly, but there are some more pricey things on this earth. Man made machines can be complex and expensive, but here we are talking about exclusive substances. This is the list of the top 10 most expensive materials in the world. We have made a list of the most expensive substances on earth by weight. This is a surprising list, and it contains many interesting elements and compounds.

There are many types of materials in this world. Some are worthless, and some are priceless. We have a very different use of each substance. So we pay the price according to its importance and availability. The price we are willing to pay to obtain anything defines value. Therefore these materials are very valuable. We also have a list of the top most dangerous chemicals in the world. They are also very interesting. Those dangerous chemicals are expensive but not as costly as the ones listed here.

Countless materials are existing in our world. We can’t list all of them according to their value. But we can find some of the most valuable and expensive ones. All these materials are expensive because they are rare, hard to find, useful, and hard to produce. We know that not everything is useful, but most of them are. Most of the materials are expensive due to demand and low availability. The top cost-driving parameters of these substances are rarity and importance.

List of Most Expensive Materials In The World

Here we have listed the top most expensive substances according to the price per gram. These prices may fluctuate due to market conditions. But they should give you a rough idea about their value.

10) Heroin

Cost: $130/gram

It is an opioid drug made from morphine. Its other name is Diacetylmorphine. The common street name is Crack. Heroin is highly addictive, and it is very harmful to health. People mix it with water and inject it. While some users snort it or smoke it. Heroin is addictive and creates resistance in the body. It means a user needs to use a higher dose each time to get the same high. If a regular addict stops using this opioid, there are withdrawal symptoms. Many abusers also catch HIV/AIDS and hepatitis while using shared needles.


9) Cocaine (Coke)

Cost: $600/gram

It is a very popular recreational drug. The street famous name is “Coke”. Cocaine comes from the Coca plant using various processes. Its biggest users in the world is North America. Its formula is C17H21NO4, and it is used in some medical procedures. The most common application in a medical procedure is a numbing agent. Cocaine is also highly addictive, and it gives a feeling of happiness, according to Wikipedia. It is usuallyy taken in many ways. This includes inhalation, snorting, and injection. Coke’s use causes a rise in blood pressure, an increase in heart rate, and pupil dilation. Over or excess dosage may cause stroke, cardiac arrest, and infarctions.

8) LSD (Lysergic Acid Diethylamide)

Cost: $3000/gram

LCD is a very popular recreational drug. Its common name in the market as “Acid”. It is shown in many movies and pop culture. The formula of Lysergic Acid Diethylamide is C20H25N3O. The effects can last for a long time, up to 12 hours. Things can be dangerous if someone is zoned out for a long time alone. The effects of LSD include high blood pressure, pupil dilation, and pyrexia. Users say that it gives a feeling of heightened sensation and feelings. LSD is mostly ingested and kept in the mouth. It actually has white color but no odor. It also has low dependency and addiction rates.


7) Plutonium

Cost: $4000/gram

Plutonium is a radioactive element with silver-gray color. Its symbol is “Pu”, the atomic number is 94, and the atomic weight is 238. Plutonium was first produced in 1940 by bombarding Uranium-238 at the University of California. This element is quite dangerous as it can accumulate in bones. Plutonium has uses in nuclear reactors, bombs, and spacecraft. Plutonium isotopes are fissile. Therefore they are used in nuclear chain reactions. It was heavily used in the Manhattan Project and Trinity Nuclear test in 1945.

6) Taaffeite

Cost: $20,000/gram

Richard Taaffe discovered Taaffeite. Its is a mineral and its formula is BeMgAl4O8, and it is one of the rarest minerals on earth. This gem consists of Magnesium, Beryllium, and Magnesium. Taaffeite is very rare mineral. It is found in Sri Lanka, Tanzania, and China in very small amounts. The uses are quite less in the scientific world. But it is in demand and therefore costs a lot.


5) Tritium

Cost: $30,000/gram

Tritium is a radioactive isotope of hydrogen. It is represented as 3H. It has a half-life of 12.32 years. Tritium is hard to find naturally on earth. However, we can find a very small amount naturally in the atmosphere. Tritium is mostly used in nuclear reactors, radioactive tracer, and radioluminescent light sources in various objects. There are many ways of producing Trinium using Lithium, Boron, and Deuterium. The production procedure is complex and very costly. This is why it is among the most expensive substance in the world.

4) Diamonds

Cost: $65,000/gram

This is the most popular thing in the world that almost everyone knows. Diamond is known as the most valuable and expensive material on the earth. It is an allotrope of carbon that forms due to heat and pressure. It has the highest hardness and thermal conductivity among all naturally occurring materials. Diamond is popularly used in ornaments and as luxury decoration. However, there are huge industrial applications. Diamonds are useful in cutting, drilling, polishing, chamfering hard materials. Diamonds are mostly natural. But there are many ways of artificial synthesizing as well. Most industries use artificial diamonds for work purpose.

3) Painite

Cost: $300,000/gram

It is a rare mineral that was first found in Myanmar. Painite is very rare, and it can cost a fortune. Its formula is CaZrAl9O15(BO3), and it mainly consists of Aluminium, Calcium, Oxygen, Zirconium, and Boron. Painite has a hexagonal crystalline structure, and it has a red-brownish color. Its rarity gives the high price in the market.

2) Californium

Cost: $27 million/gram

Californium is an exceptional radioactive element with atomic number 98. Its symbol Cf and it is costly. Californium was discovered in 1950 at the University of California by bombarding Curium. This is why the name comes after the American state. The half-life of Californium-252 is about 2.645 years. Its use is in nuclear reactors and other radiation work. Scientists use “Cf” coal analysis, neutron emitter, and radiation therapy for treating cancers. Californium can be dangerous to bones, skeletal muscles, and liver.


1) Antimatter

Cost: $100 Trillion/gram

It is the most interesting and most expensive materials on earth. In physics, particles make up materials. But antiparticles make up antimatter. For example, there is antiproton for proton; there is antineutron for neutron. They are very hard to make and catch. Antimatter is also created in a very small amount in particle accelerators like at CERN. Cosmic ray collisions and radioactive decay also crate them in small amount in the universe. Tracing antimatter is also very hard and needs a lot of sensors.

In theory, the collision of particle and antiparticle can cause annihilation. A proton has a positive charge in common knowledge, and the electron has a negative charge inside an atom. Antiproton also has a negative charge but the same mass as the proton. So Antiproton is the antimatter to Proton.

Other Expensive Substances in the World

There are many other expensive substances in this world. We also wanted to mention them for you.

  1. Saffron: $12/grams
  2. Gold: $60/grams
  3. Platinum: $55/grams

Saffron is one of the most expensive spices in the world. It comes from a plant named Crocus sativus. People use this spice in food and sweets. The aroma and taste of Saffron is very good. The saffron comes in small crimson threads, and they give both color and taste. India, Iran, Afghanistan, Greece, Italy, Spain, Australia, China, Africa, are some major producers in the world.


Gold is a very precious metal, and it has high value due to its properties. Color and attraction are the main causes of its price. We also make ornaments and jewelry from Gold. People like it, and they buy it as property and movable assets. Gold coins have been long used for trading for a long time. People also invest in gold like dollars. The price change also happens in a wild manner. This is all due to interest, attraction, and market investment. Many electronics and industrial purposes need Gold. Our smartphones, laptops, and computers have traces of gold inside boards and circuitry.
