What is the difference between cultivating diamonds and natural diamonds?

The price is different: the cultivated diamonds are artificially synthesized, and the price is lower. The cultivation of diamonds is to convert the carbon of non-diamond structure into the carbon of the diamond structure through the formation conditions of natural diamonds, and finally form the cultivation of diamonds.

The formation method is different. CultivationThe breeding diamond is that after the seed diamond is put into the vacuum chamber, it is introduced with mercury and then heated to 3000℃ methane and hydrogen to form a high-charged plasma. Then the two gases decompose and release carbon atoms, which will form the crystal structure of the diamond. Natural diamonds are naturally formed.

The price is different: the cultivated diamonds are artificially synthesized and the price is low. The cultivation of diamonds is the formation conditions of man-made simulation of natural diamonds, so that the carbon of non-diamond structure is converted into carbon of diamond structure, which becomes the cultivation of diamonds.

The difference between natural diamonds and artificially cultivated diamonds Mineralization process: It takes millions or even billions of years to form natural diamonds; while artificially cultivated diamonds can be completed in a short time in the laboratory. Chemical composition: The differences between them can be distinguished through professional testing equipment, such as diamond identification instruments, spectrometers, etc.

The difference between cultivating diamonds and natural diamonds is as follows: the formation method, the cultivation of diamonds is to artificially enter the seed diamonds through technical means to form a diamond crystal structure, while natural diamonds are naturally formed, not artificially manufactured. Characteristics, a small number of cultivated diamonds can be adsorbed by absorbent iron stone, while natural diamonds cannot be absorbed by iron stone.

The difference in price is also one of the main differences between cultivating diamonds and natural diamonds. Cultivated diamonds are man-made diamonds, and their price is much lower than that of natural diamonds, because this kind of diamond can be artificially synthesized, and its output is greater than that of natural diamonds. Different characteristics. The main difference between cultivated diamonds and natural diamonds lies in their characteristics.

What have the villagers in Zhangqiao Town, Henan Province experienced from 500,000 to 20,000?

The difficulty of changing customs is not being able to "play a game of chess". The progress of various townships is also uneven. Zhangqiao Town changed quickly, and the dowry was uniformly set at less than 20,000 yuan. Anping Town is far away from the city, and the dowry is heavy. Generally, it is more than 100,000 yuan, and it is reduced to 50,000 yuan first. If you change customs, you can't just blow "a gust of wind".

The villagers' dowry of 60 yuan and 300,000 yuan in cash has caused a heated discussion on the Internet. This phenomenon reveals that the sky-high dowry still exists, and the comparison between relatives also exists, which can also show that the work of the relevant departments may not be done well.

Why does this kind of sky-high dowry often appear? It is understood that the dowry in the video is a dowry given by a person from Shangqiu, Henan Province. There are 60 kinds of large items, 8 pieces of Huazi, a whole pig and a whole sheep, more than 10 boxes of fruit, and more than 300,000 yuan in cash.For an ordinary family, this can definitely be regarded as a sky-high dowry.

The object of marriage is not money, but people: and we should think about it. Our marriage partner is not the so-called miserable money in the world, that is, tens of thousands of yuan. Everyone can still accept it. You can buy a dowry of up to 300,000 yuan, which can be bought directly in full in some third-tier cities. Suite room.

Zhang Zhanli is very old. When he is 30 years old, he can't see the shadow of his wife, so he is also very eager to have a wife, even if she is not beautiful.

But the man thinks that this is because the woman wants a high-priced dowry and needs to be repaid together, then the conflict between the two sides will intensify, and eventually it will even end in divorce.
