Known as the queen of precious stones, diamonds possess timeless beauty and great economic value. So who was there? diamond formation process How is it or not? Let's find the answer in the article below!

Diamond formation from underground

Diamond is one of the two best known allotropes of carbon (the other is graphite), with a very high hardness and excellent refractive properties that give it a wide variety of applications in both industry and commerce. jewelry industry.

Diamonds are formed from carbon-containing minerals under very high temperatures and pressures. On Earth, everywhere can have diamonds because at a certain depth, there will be a high enough temperature and high enough pressure to form diamonds. On continents, diamonds begin to form at depths of about 150 km (90 miles), where pressures are about 5 gigapascals and temperatures are about 1,200 degrees Celsius (2,200 degrees Fahrenheit). In the ocean, this process occurs in deeper areas because the temperature needs to be higher, so the pressure is also higher. As the pressure and temperature gradually decrease, the diamond also grows larger.

Scientists have suggested that diamonds were formed a long time ago, about 1 billion to 3.5 billion years. Diamond formation takes place under extremely rare physical conditions, but it is created from one of the most abundant basic elements in nature, carbon. Crystallization occurs under demanding physical conditions, where pressures exceed 5 gigapascals (GPa) and temperatures reach over 1300°C, equivalent to conditions at depths of 100-200 km underground. .

When diamonds are brought close to the surface by lava tubes, they can "leak" across a large surrounding area. A lava tube is considered the main source of diamonds. There are also some diamonds scattered due to external factors (environment, water source). However this amount is not large.

Diamonds can also be brought to the surface during continental breaks, although this is not clearly understood and is rare.

The formation of diamonds from outer space

Diamonds can also be formed in other high pressure and temperature phenomena. People have found extremely small diamond crystals in the heart of meteorites. It is these diamond dust particles that modern scientists use to determine the location of meteorites falling to earth.

Modern scientists have found traces and proven that diamonds exist on Uranus, Neptune and other planets, and there is even diamond rain on Jupiter and Saturn.

Above is information about the formation process of diamonds C Jewelry Diamond provide you. Hopefully, you will have more useful information for yourself.
