How exactly are diamonds formed?

We often see large and small shining diamonds in our lives, but we have never known how diamonds come from and how they are formed. The rough diamonds belong to diamonds, and diamonds become diamonds after being processed and polished. So how do diamonds often see large and small shining diamonds in our lives, but we have never known how diamonds come from or how they are formed. The rough diamonds belong to diamonds, and diamonds become diamonds after being processed and polished. . So how is diamond formed? Let's take a look with the author below. Let's take a look with the author below!　　　　 Diamond is derived from the ancient Greek Adamant, which means a hard and inviolable substance. The hardness of diamond is the highest among natural minerals. Diamond is actually a very dense carbon crystal. Since diamonds were discovered in India, people have picked up diamonds by rivers and beaches. This is because the original rock containing diamonds located somewhere in the upper reaches of the river is weathered and broken, and the diamonds are taken to the downstream area with the current. Large diamonds are buried in the gravel. How do diamonds form? Scientists have studied the primary inclusions of diamonds from different mines in the world and found that diamonds are carbon-rich deposits more than 100 kilometers below the surface. They are under huge pressure and high pressures of 1200 degrees Celsius. Formed under the environment. The vast majority of diamonds were formed between 2 billion and 3 billion years ago. This complex and severe process has changed the arrangement of molecules tremendously, turning them from black carbon blocks into surprisingly fascinating transparent diamond crystals. This is what we often call white diamonds. The formation of colored diamonds is due to the fact that other elements are mixed in during the process of carbon element change, so that the transparent diamond crystals derive colorful colors, such as blue diamonds, yellow diamonds, red diamonds and so on.　　　　From the complex formation conditions of diamonds, diamonds are indeed a rare gemstone. At present, the main diamond producing areas in the world are Australia, Southern Africa, South Africa, Russia, China, etc. Although the formation conditions of diamonds are complicated, the rarity of rough diamonds is caused, but what makes diamonds rare and precious is not only the rarity of rough diamonds, but more importantly, the skill of polishing rough diamonds. The exquisite polishing process can make a rough diamond become one. Exquisite precious diamonds.　　　　 In short, diamonds are the oldest gemstones in the world. Its formation requires a long historical process, which can be confirmed from the fact that diamonds are mainly produced in ancient stable continental areas on the earth. In addition, it is said that the impact of extraterrestrial bodies on the earth produces instantaneous high temperature and high pressure, which can also form diamonds.　　　　 The above is the information summarized by the author about the source of diamonds.
