There are four main processes that control the formation of diamonds, using extreme temperature (over 2,700 degrees Fahrenheit) and pressure (at least 725,000 pounds per square inch, or the pressure of 4,000 grown men standing on your foot).
What are the four main ways that diamonds formed on Earth?
There are four natural methods of diamond production, consisting of Formation in the Mantle, Formation in the Subduction Zone, Impact Zones, and Space Formation. Kimberlite, an igneous rock that has become synonymous with diamonds, forms deep in the Earth’s mantle and is forced to the surface by volcanic eruptions.
What process forms diamonds?
A mined, natural diamond is a crystallized carbon structure that is formed beneath the earth’s surface over millions (or sometimes billions) of years under the perfect conditions of heat and pressure. The diamonds are brought to the surface during natural events (like volcanic eruptions) and then mined from the land.
How do diamonds really form?
Diamonds are made of carbon so they form as carbon atoms under a high temperature and pressure; they bond together to start growing crystals. … As other carbon atoms move into the vicinity they will attach on. That’s the way any crystal grows.
How diamonds are formed pressure?
The conditions surrounding how diamonds are formed are precise and intense. … Under the duress of approximately 725,000 pounds per square inch, and at temperatures of 2000 – 2200 degrees Fahrenheit, a diamond will begin to form. The carbon atoms bond together to form crystals under this high pressure and temperature.
Is coal a diamond?
How Are Diamonds Formed? As we suggested before, diamonds form underground at high pressures and high temperatures, which likens them to coal in a way. Despite this small similarity in origin, however, diamonds are arguably nothing like coal.
Where Can diamonds be found?
Natural diamond has been discovered in 35 countries. Some diamonds have been found in the United States. Colorado, for instance, has produced a small number of diamonds. The following countries produce industrial grade diamonds: Australia, Botswana, Brazil, China, Congo, Russia and South Africa.
What is the biggest diamond in the world?
The largest stone is called the “Star of Africa I,” or “Cullinan I,” and at 530 carats, it is the largest-cut fine-quality colorless diamond in the world. The second largest stone, the “Star of Africa II” or “Cullinan II,” is 317 carats.
How diamond is cut?
Diamond cutting is done by cleaning or sawing the diamond with a steel blade or a laser like the Sarine Quazer 3. The rough diamond is usually placed in a wax or cement mold to hold it in place and then cleaved along its tetrahedral plane, its weakest point. If no point of weakness exists, instead sawing is used.
What can you craft with diamonds?
A diamond is a rare mineral obtained from diamond ore or loot chests. They are mainly used to craft high-tier tools and armor, enchanting tables, blocks of diamond, and jukeboxes.
Can Gold Break diamond ore?
The diamond ore block itself (rather than its diamond drops) can be obtained by mining it with an iron, diamond or netherite pickaxe with the Silk Touch enchantment. When mined without Silk Touch, diamond ore drops a single diamond.

Are there diamond Stars?
About 900 light-years away, an ancient white dwarf star has cooled into a crystallized chunk of carbon — a diamond. … The diamond-star, described in a study published in The Astrophysical Journal, is among the coldest white dwarfs astronomers have found.
How diamond is formed from coal?
Over the years it has been said that diamonds formed from the metamorphism of coal. According to Geology.com, we now know this is untrue. “Coal has rarely played a role in the formation of diamonds. … The diamonds form from pure carbon in the mantle under extreme heat and pressure.
What do diamonds do under pressure?
“Diamonds are formed under pressure, but never forget, they are not formed overnight.” In nature, diamonds are formed under pressure and heat causing carbon atoms to crystallize and form coveted diamonds. Diamonds are found 150–200 kilometers below the Earth’s surface.
