In his quest to mimic conditions deep inside the Earth, Dan Frost of the Bayerisches Geoinstitut in Germany has discovered a way to turn peanut butter and carbon dioxide into diamonds. The process essentially extracts the oxygen from CO2, leaving behind carbon that, under intense pressure, and form diamonds.
And that is exactly what Frost found when he recreated the process using his presses — essentially forging a diamond from thin air. In a diamond, the carbon atoms are arranged tetrahedrally. Each carbon atom is attached to four other carbon atoms 1. It is a strong, rigid three-dimensional structure that results in an infinite network of atoms.

The most convincing evidence that coal did not play a role in the formation of most diamonds is a comparison between the age of Earth's diamonds and the age of the earliest land plants. Most of the rock-hosted diamond deposits that have been found were formed during the Precambrian Eon - the span of time between Earth's formation about 4, million years ago and the start of the Cambrian Period about million years ago.
In contrast, the earliest land plants did not appear on Earth until about million years ago - nearly million years after the formation of the vast majority of diamonds that have been mined. Since coal is formed from terrestrial plant debris, and the oldest land plants are younger than almost every diamond that has ever been dated, it is easy to conclude that coal did not play a significant role in the formation of Earth's natural diamonds.
In the s, new methods of diamond formation were discovered on Earth's surface. Scientists were able to create the temperature and pressure conditions needed to create diamonds in a lab. Most of the early diamonds were not gem quality, but they were perfect for use as abrasive granules in drill bits, cutting tools, and grinding wheels.
Soon larger lab-grown diamonds were being manufactured for use as wear-resistant bearings, heat sinks for computer processors, and high-temperature windows. Today almost all of the diamonds used in industrial processes are lab-created diamonds. They are also being made in high enough qualities to earn colorless and very very slightly included grades from diamond grading labs.
They are made in a spectrum of colors by adding nitrogen yellow or boron blue to the diamond-forming environment. Green , pink, orange and other colors are possible with post-growth treatment processes. Lab-created diamonds are being made in the United States and several other countries. China is the leading country producing lab-created diamonds. All lab-grown diamonds are made using equipment that consumes an enormous amount of electricity, which is needed to create the temperature and pressure conditions necessary to grow diamonds.
Some of that electricity is likely to be generated from burning coal. These might be the best examples of diamonds being made using coal. How Do Diamonds Form? Contrary to what many people believe, diamonds do not form from coal.

While the recipe for natural diamonds may be quite complex and time consuming to say the least, creating synthetic diamonds is a lot simpler. Another method for creating synthetic diamonds is called Chemical Vapor Deposition.
This requires an actual diamond and uses less pressure and more heat. The diamond is placed in a depressurizing chamber where natural gas is zapped at it through a microwave beam.
After being heated to nearly 2, degrees, carbon atoms begin to form and fall down upon the diamond, thereby sticking to it, expanding it, and ultimately creating what looks as an almost flawless stone. Yes, real diamonds take an extremely long time to form.
That is the main reason they are so expensive, beautiful, and indestructible. Not only that, but these sources don't even provide context for the quote.
And if Kissinger didn't unleash this beast of a proverb out into the world, he can always give us a call to set the record straight. Whether or not he actually ever said the words, however, is technically a moot point for the purposes of our discussion.
Kissinger is the universally agreed upon voice of the wisdom espoused in the quote, so we'll have to content ourselves with that fact—at least for now. In any case, Kissinger's adage, while motivational, was factually incorrect when he supposedly uttered it years ago, and it's still wrong today. No one can say for sure that he knew this at the time, but we can all say that the saying has certainly become a real gem of its own, pun intended.
As we indicated before, Kissinger's motivational proverb has no factual basis. Despite that fact, we must admit that the saying at least tries to understand how diamonds actually form. That is to say, diamonds do share some properties with coal, albeit not extremely significant ones. In order to understand these similarities a bit more, we'll briefly discuss how both coal and diamonds form beneath the surface of the earth. Like diamonds, coal forms deep underground under high pressure and high temperatures.
