In case you were ever wondering, here are ten of the world's most expensive materials on Earth by weight. Some are ridiculously expensive.
by bombarding curium with alpha particles. This reaction creates the radioactive chemical element with an atomic number of 98.It can help treat certain forms of cancer, detecting gold and silver in ores and residual oil within nearly depleted reservoirs. It can only be created artificially on Earth but is speculated to be made in supernovae.have long been prized for their beauty and extreme hardness.
Cost 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. High-carat blue diamonds can go for upwards of $4 million per carat.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.
Their hardness gives them many industrial applications, but synthetic rather than natural diamonds are used. Artificial equivalents are also a lot cheaper to buy. Diamond jewelry is one of the most popular choices for engagement rings.in the hearts of nuclear reactors by irradiating lithium metal or lithium-bearing ceramic pebbles. It is also one of the most expensive materials on Earth. It is a super heavy type of hydrogen.
Tritium is also a key component used to fuel some nuclear weapons. It is sometimes used for "glow in the dark" stuff like watch hands and as a tracer in biomedical and academic research. Have no fear, though; the beta rays it produces are very weak and can't penetrate human skin. 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.that has only recently become desirable by collectors.
So rare is this gemstone that, according to some sources, all of the discovered ones would fill half a cup.
