Most Expensive Materials On Earth By Weight (per gram)

Most Expensive Substances In The World By Weight (per gram)

The most expensive substance on earth by weight tend to be expensive because of their rarity or because of the difficulty in producing them. However, some materials have an inflated value because of the criminal risk involved in buying and selling these items.

Over time, the worth of expensive substances regularly changes as the availability of rare materials increases, or the desire for them decreases. Elements like helium are relatively inexpensive, but as the world’s supply eventually dwindles as it’s predicted to, this elemental gas may experience a surge in market value.

10 Most Expensive Materials  On Earth By Weight (per gram)

Our top 10 list with The Most Expensive Materials On Earth By Weigt is dominated by rare earth elements such as platinum, precious gems like diamonds and advanced materials that are dangerous and hard to produce. All of these substances share a common thread of being high in demand and low in supply – except for those outliers which have been declared illegal in most countries on the planet. This list with the top 10 most expensive substances in the world does not include drugs which are listed seperatly.

11. Gold – $56 per gram

Gold,  79Au

Gold is an incredibly expensive substance. Gold is a chemical element with symbol Au (from Latin: aurum) and atomic number 79. It is a bright yellow dense, soft, malleable and ductile metal. The properties remain when exposed to air or water. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements, and is solid under standard conditions. The metal therefore occurs often in free elemental (native) form, as nuggets or grains, in rocks, in veins and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).

Gold’s atomic number of 79 makes it one of the higher atomic number elements that occur naturally in the universe, and is traditionally thought to have been produced in supernova nucleosynthesis to seed the dust from which the Solar System formed. Because the Earth was molten when it was just formed, almost all of the gold present in the Earth sank into the planetary core. Therefore most of the gold that is present today in the Earth’s crust and mantle is thought to have been delivered to Earth later, by asteroid impacts during the late heavy bombardment, about 4 billion years ago.

Gold has been a valuable and highly sought-after precious metal for coinage, jewelry, and other arts since long before the beginning of recorded history. In the past, a gold standard was often implemented as a monetary policy within and between nations, but gold coins ceased to be minted as a circulating currency in the 1930s, and the world gold standard (see article for details) was finally abandoned for a fiat currency system after 1976.
