How are diamonds formed? How diamonds are formed

In fact, the conditions for the formation of most diamonds are the same as those for the formation of man-made diamonds, which require a state of high temperature and high pressure, and the formation of diamonds in the natural environment requires such a state of high temperature and high pressure. For the natural environment, the natural environment in which a diamond can provide such a high pressure and intensity is about 150 to 200 kilometers underground. The required temperature needs to reach about 1500 degrees.

Such strict physical and chemical conditions can only be achieved in the depths of the earth.

But in fact, most of the natural diamonds produced in nature are 2 billion or even 3 billion years ago. At present, the oldest diamond found by mankind can even reach about 4.5 billion years old. In general, the natural diamonds that we can obtain today are brought to the surface through lava from volcanic eruptions.

These diamonds are exposed to the wind and sun in rivers and other places for many years. That's why it's possible to be exploited.

But in the current market, we can buy diamonds, in fact, a considerable part of them are artificially produced, and the annual production of diamonds in our country is also very high, so the current natural diamonds are very expensive, and we usually buy diamonds through a simple tens of thousands, or even 10,000 pieces, that are artificially created artificial diamonds. If there is a chance to buy a natural diamond, it is very collectible.

In addition to this cause, there is another reason for the formation of diamonds, which is believed to be the high-temperature and high-pressure state generated when a planet hits the earth, which transforms graphite into the diamond state we see. Scientists speculate that 15 million years ago, an asteroid with a diameter of about 1 km hit the earth's surface. At the same time as the impact, a crater with a width of 25 km was created, and the carbon bubbles around the inside of the crater instantly turned into tiny diamonds with a diameter of less than about one under high temperature and pressure, which were barely visible to the naked eye.

Diamond is actually a regular row of carbon, 150 kilometers underground, the pressure reaches 5 million kilopascals, the temperature exceeds 1200 degrees, after tens of thousands of years of high temperature and high pressure formation.

The essence of diamond is diamond, and then it is a carbon atom, which is a kind of atom and the coal we usually see, but due to various external factors, high temperature, high pressure, the carbon atom of diamond and the carbon atom of coal are arranged in different orders, forming different substances.

In one case, 2 billion to 3 billion years ago, the high temperature and high pressure in the Earth's interior changed the structure of carbon to form diamonds, and the other was when graphite-carrying meteorites hit the Earth.

Its composition is basically the same as that of coal, pencil lead and sugar, and carbon crystallizes to form graphite (black) at high temperature and pressure, and crystallizes into precious diamonds (colorless) at high temperatures, extremely high air pressure and in a reducing environment (usually a hypoxic environment).

Since diamonds were discovered in India, diamonds have been picked up on rivers and beaches, because the original rock containing diamonds somewhere upstream of the river has been weathered and broken, and the diamonds are carried downstream with the current, and the diamonds with a large gravity are buried in the sand.

Origin distribution of diamonds:

There are diamonds all over the world, and more than 30 countries have diamond resources, with an annual output of about 100 million carats. The top five countries in terms of production are Australia, Zaire, Botswana, Russia, and South Africa.

These five countries account for about 90 per cent of the world's diamond production. Other diamond-producing countries include the Democratic Republic of the Congo, Brazil, Guyana, Venezuela, Angola, Central Africa, Ghana, Guinea, Ivory Coast, Liberia, Namibia, Sierra Leone, Tanzania, Zimbabwe, Indonesia, India, China, Canada, etc.

The world's major diamond cutting centers are: Antwerp (Belgium), Tel Aviv (Israel), New York (USA), Mumbai (India) and Bangkok (Thailand). Antwerp has"The diamond capital of the world"About half of the world's diamond trade is done here, and the "Antwerp cut" is synonymous with the perfect cut.

There are two ways in which diamonds are formed, one is formed by the high temperature and pressure of the earth, and the other is formed by graphite-carrying meteorites and the impact of the earth, both of which are more demanding, so diamonds are very precious. Most of the diamonds on the market are formed under high geological temperature and high pressure, and the formation location is deep in the earth, and the temperature is between 1100 and 1500.

Causes of diamond formation.

For some shiny and beautiful things, people are often very difficult to refuse and absolutely eye-catching, such as diamonds, jade, etc., which are very popular in the market, and are often made into a variety of jewelry for the Sui people to wear, so how is a substance like diamond formed, is it endless?

Regarding the formation of diamonds, there are actually two ways, one is formed by the high temperature and high pressure of the earth, and the second is formed by meteorites hitting the earth, and whatever the reason, it shows that diamonds are very precious and rare, so most of the diamonds sold on the market are very expensive.

At present, most of the diamonds on the market are formed under the condition of high geological temperature and high pressure, and the temperature is generally between 1100 and 1500, and the position of the shape is about 150 200 kilometers below. In addition, when a meteorite carrying a stone mill hits the earth, the high temperature and high pressure generated by the impact can also convert the stone mill inside into diamond, and the diamond is a common diamond after being carved.

Formation of diamondsDiamonds can be broadly divided into naturally occurring diamonds and artificially formed diamonds. Naturally occurring diamonds are generally formed under high temperature and high pressure in geology, and their temperature needs to reach about 1100 to 1500 degrees Celsius and the pressure can reach 6 gpa. Diamonds are generally found at depths of 150 to 200 km underground.

An introduction to diamondsDiamond is a type of diamond, a mineral composed of the element carbon, which is an allotrope of graphite. Diamonds are commonly used as handicrafts or as cutting tools in industry. The reason why it can be used in this area is because diamond is the hardest substance that occurs naturally in nature.

Summary. Diamond is a kind of elemental crystal composed of carbon formed under high temperature and high pressure conditions, which is brought to the surface by magma through volcanic eruptions, and the temperature needs to reach about 1,100 degrees Celsius to 1,500 degrees Celsius, and the pressure reaches 6 gpa.

It is known that the uncorrupted rock is a kind of elemental crystal tremor composed of carbon elements formed under the conditions of high temperature and high pressure, which is brought to the surface by magma through volcanic eruptions, and the temperature needs to reach about 1,100 degrees Celsius to 1,500 degrees Celsius in Chakai, and the pressure reaches 6 GPA.

Diamonds can become dull if left uncared for. Here are some tips I have for you when wearing them:1

Diamonds should not collide with hard objects to hail and sell; 2.Keep away from oily substances. When washing dishes or doing housework, remember to take them off and leave them alone; 3.

Avoid contact with perfumes, cosmetics, etc., to prevent affecting the luster of the diamond. That's all for you, I hope it can help you. <>

Data development] This is my content for you about the value of diamonds, I hope it can help you Investment value: The ** of diamonds is rising every year, generally about 3%-5%; Collectible value: Diamonds have excellent physical properties and their rarity characteristics, and the collection price of diamonds is huge.

Diamond is the only gemstone variety that combines the highest hardness, a strong refractive index and high dispersion in the rock, outperforming other gemstone varieties. Practical value: Diamonds are special gemstones that are beautiful, durable and rare.

The rarity of diamonds makes it extremely expensive, and wearing diamonds can show your status.
