![]() The mineral comprises calcium, zirconium, boron, aluminum, and oxygen. Painite can cost anywhere from $50,000 to $60,000 per carat due to its scarcity. The mineral was named after it was determined to be a brand-new mineral species. ![]() Pain, who mistakenly thought it was ruby. It was recognized as a new gemstone in the 1950s and was initially discovered in Myanmar by British mineralogist and gem trader Arthur C.D. Painite is another very expensive material and possibly one you've never heard about. Painite is another scarce and very expensive materialĬost per gram: Around $300,000 (or up to $60,000 per carat) So rare is this gemstone that, according to some sources, all of the discovered ones would fill half a cup. The primary source for these gems is Tanzania. It has color ranges from red to purple, and there are thought to be less than ten of the rarest red ones in existence. Taaffeite is an incredibly rare gemstone that has only recently become desirable by collectors. 6. Taaffeite stone is a very new gemstoneĬost per gram: about $20,000 ($1,500 to $2,500 per carat) Tritium also has a shallow health risk if ingested, though you should probably rethink your life if you're in the habit of eating it. Have no fear, though the beta rays it produces are very weak and can't penetrate human skin. It is sometimes used for "glow in the dark" stuff like watch hands and as a tracer in biomedical and academic research. Tritium is also a key component used to fuel some nuclear weapons. It is also one of the most expensive materials on Earth. Tritium is forged in the hearts of nuclear reactors by irradiating lithium metal or lithium-bearing ceramic pebbles. Tritium can only be forged in nuclear reactions Diamond jewelry is one of the most popular choices for engagement rings. Artificial equivalents are also a lot cheaper to buy. Their hardness gives them many industrial applications, but synthetic rather than natural diamonds are used. Their blue color comes from the element boron. Blue diamonds are incredibly rare and are found in just three areas: Australia, South Africa, and India. ![]() These stones are forged at the very depths of the Earth's crust and upper mantle and, as such, have experienced intense temperatures and pressures. High-carat blue diamonds can go for upwards of $4 million per carat. They are the hardest substance known on Earth, with a Moh's scale score of 10 and a Vickers hardness in the range of 70–150 GPa.Ĭost varies widely depending on the diamond in question, with some, like "blue diamonds," fetching $26,280 on average for a 0.5-carat stone and deep blue and vivid blue diamonds costing around $75,000 for a 0.25-carat stone. Natural diamonds have long been prized for their beauty and extreme hardness. Diamonds are notoriously expensive thingsĬost: $1,500 to $100,000 plus per carat, depending on purity, color, etc. It can only be created artificially on Earth but is speculated to be made in supernovae. It can help treat certain forms of cancer, detecting gold and silver in ores and residual oil within nearly depleted reservoirs. There are currently ten known isotopes known to exist. This reaction creates the radioactive chemical element with an atomic number of 98. Scientists create californium by bombarding curium with alpha particles. Californium is another costly material by the gramĬost per gram: $10 to $27 Million ($10 to $27 per microgram) It could have applications for highly accurate atomic clocks.Ĭurrently, two varieties exist, endohedral metallofullerenes and non-metal doped fullerenes. It is, essentially, a cage of carbon atoms with a nitrogen atom trapped inside. The very first lanthanum complex was created in 1985. 2. Endohedral fullerenes will cost you a fortune per gramĬost per gram: $145 million to $167 millionĮndohedral fullerenes are normal fullerenes with extra atoms, ions, or clusters within inner spheres. Today, a gram of antimatter, if it were available, would be worth approximately $80 trillion. It requires the highly sophisticated technology found at places like CERN to even dream of "making it." Although only very small amounts have ever been produced, there is currently no way of storing them. Antimatter is so rare it costs trillions per gramĬost per gram: Between $62.5 and 100 trillionĪntimatter is by far the most expensive material on Earth. So, without further ado, let's get into it, shall we?īefore we start, please note that the list below is not meant to be complete and is not in any particular order. Some of these expensive materials result from human work and are high-tech, while others can be found in nature. Others are from sources of advanced materials that are very hard to produce.
