Many of us thought that gold and diamonds are one of the most expensive materials in the world. Apparently there are more than these widely known costly rock materials. Here’s a spoiler, do you know that a rhinoceros’s horn is highly valuable? If you want to know more, just head on these 10 most expensive materials in the world that you might not know. Check them out below.
10. Saffron — $11 per gram
Saffron is a unique combination of fantastic taste and great health benefits in one spice. While the production process is highly time and effort consuming, the flavor and healing properties of saffron are unmatched.
9. Rhodium — $58 per gram
It’s an extremely rare metal from the platinum group. To give you the big picture, let’s say that one ton of earth crust contains about 0.001g of rhodium.
8. Platinum — $60 per gram
A rare and precious metal of a silvery steel color which we often hear when artist reaches a certain record sales. But like gold, it’s highly resistant to acids, alkali, and other compounds.
7. Rhinoceros’s horn — $110 per gram
The horns are valuable for their medicinal properties and as great knife handles. Because of poachers, poor rhinos are already on the verge of extinction.
6. Plutonium — $4,000 per gram
A heavy yet fragile radioactive metal of a silvery-white color. Its uses vary from production of nuclear weapons and fuel to a source of energy for spacecrafts. Remember Chernobyl?
5. Painite — $9,000 per gram
Painite is a rare mineral of an orange or reddish-brown color, and it was only discovered 65 years ago. There are just a couple hundred of these stones in the world today.
4. Taaffeite — $20,000 per gram or $4,000 per carat
Taaffeite is a million times rarer than diamonds, this what makes this precious stone of a violet, pink, red, or white color legendary. However, despite its uniqueness, it’s not very popular when it comes to jewelry — and that’s probably the reason why it’s relatively inexpensive.
3. Tritium — $30,000 per gram
This gas is used in lighting — for example, in tritium illumination. It costs about $15 million to produce a pound of tritium.
2. Californium — $25-27 million per gram
The most expensive chemical element ever. It has been synthesized only once since its discovery in 1950.
1. Antimatter — $62.5 trillion per gram
The most expensive substance on Earth. In theory, we will be able to use antimatter as fuel for spacecrafts in the future. But the drawback today is that to make just one gram of it costs about $25 million. Which means all of mankind will have to work for about a year without rest.
