How are diamonds formed? Why is diamonds so expensive?

Diamonds are very expensive gemstones and are natural minerals. Just because diamonds are expensive does not mean that they are rare.

 

Diamonds are 99% made up of the element carbon, which can form naturally in the high temperature and high pressure environment of the earth, carrying carbon elements such as graphite Meteorites can also form diamonds if they strike the Earth, creating a high temperature and high pressure environment.

 

Compared to gold, the conditions for the formation of diamonds Diamonds are not difficult to form, so there are no shortage of diamond mines on the planet, and lab diamonds can be made by synthetic means.

 

If diamonds are not rare, why are they so expensive? This is because diamonds have been perfectly commercialised, with commercial hype that has given diamonds an unusually high price. The formation of a diamond is not complicated: the Although diamonds may look very shiny, the essence of a diamond, is the element carbon. The three common substances of which carbon is composed are activated carbon, graphite and diamonds.

 

The element carbon is very common on earth, and in the universe, after undergoing hydrogen-helium nuclear fusion, helium-carbon fusion occurs, which can form large amounts of elemental carbon. All stars can form carbon through nuclear fusion, so the universe is also very rich in carbon There is a lot of it.

 

After the formation of carbon, it gravitationally collects on rocky objects, which gradually gather to become planets. The high pressures and temperatures inside the planets allowed the carbon to form diamonds. Graphite is also a major component of carbon, and if a meteorite carrying large amounts of graphite were to hit the Earth, the pressure and temperature generated by the impact would also allow the meteorite to form diamonds. 

 If a meteorite carrying large amounts of graphite were to hit the Earth, the pressure and temperature generated by the impact could also turn the graphite within the meteorite into a diamond, but these diamonds are relatively rare and few in number.

 

The pressure required to form a diamond is 5 million times the atmospheric pressure and the temperature must be at least 1,100 degrees Celsius. Naturally occurring diamonds are hidden deeper in the earth and often close to magma.

 

The few diamonds that do occur are also subject to geological The few diamonds that are naturally occurring in the Earth are hidden at greater depths, often close to magma, due to geological movement. At present, diamond mines are largely concentrated below 160 kilometres from the surface. This makes the mining of natural diamonds more difficult.

 

However difficult it may be to mine, the essence of a diamond is still carbon, which makes it possible to synthesise diamonds. However However, it is difficult to meet the pressure and temperature required for diamonds in an artificial environment, so only industrial diamonds can be synthesised at present.

 

It is highly unusual for gold, a precious metal, to be less valuable than diamonds. In the solar system, the nuclear fusion of the star, the Sun, makes it possible to form large amounts of carbon, but the entire solar system, for example, is unable to form gold element. As a heavy element, it takes a supernova explosion in the universe to form a nuclear fusion reaction violent enough to form gold element.

 

Controlled nuclear fusion is difficult for humans to accomplish, and gold is basically impossible to synthesise artificially. But as technology development, pure diamonds can certainly be synthesised by artificial means.

 

Why are diamonds so expensive?

 

Why are diamonds so expensive when they are only carbon? This is due entirely to the commercialisation of diamonds.

 

When diamonds were first discovered, they were thought to be very rare and naturally very expensive, but with the discovery of diamond mines, the price of diamonds The price of diamonds began to fall gradually as diamond mines were discovered. The discovery of huge diamond mines in Africa threw the diamond market into complete chaos, and to avoid a drop in diamond In order to avoid a drop in prices, diamond merchants quickly devised a business plan.

 

Firstly, the diamond merchants united to monopolise the diamond industry, limiting the amount of diamonds that could be mined to avoid a price drop due to the excess of diamonds, and then The businessmen began to tie diamonds to love by planting diamond advertisements in many romance films, a decision that was so successful that Contemporary love is basically inseparable from diamonds.

 

After avoiding the mass mining of diamonds and completing the promotion of diamonds, businessmen began to drill into diamond cutting, setting diamond clarity, brilliance and other attributes, thus giving diamonds more room to rise in price.

 

As a natural gemstone of the earth, diamonds are a world away from other gems because of The diamond is a natural gemstone of the earth, and the difference between it and other stones comes from the propaganda of diamond traders. Although the number of diamond mines is increasing and production is very high, all diamond traders do not want the price of diamonds to drop. As a result, a very systematic pricing scheme began to develop.

 

Diamonds began to be compared on the basis of carat weight, brilliance, clarity, hardness, cut and many other aspects, thus raising the price of the better diamonds in each area. The price of the better diamonds in each aspect.

 

For diamonds to form, the element carbon needs to be given greater pressure and higher temperatures. There is a large amount of elemental carbon within the Earth, and there is a chance of producing diamonds at locations below 160 kilometres from the surface where high temperature environments can be generated. If mankind's mining capabilities continue to improve, there are bound to be larger diamond mines deep within the earth's crust, and as human technology improves, so will the production of man made diamonds.

 

Diamonds are more expensive because they are more difficult to mine and because diamond dealers have perfected the commercial treatment of diamonds. As a result, the price of diamonds is higher than that of other natural stones.
