Following the needs of industry and luxury goods, the pursuit of humans against diamonds has reached a wild field. Such giant diamonds such as "Kalinan" and "Leceidi La Rhone" are highly sought after.
Later, a new study by American scientists revealed the mystery of the birth of these giant diamonds on the test, and why humans rarely collect such giant diamonds.
Experts from the American Gemological Institute who participated in the seminar showed that the researchers selected more than 30 large diamonds from hundreds of thousands of diamonds, the largest of which was about 400 carats. They examined the trimmed cuts of diamond processing, and in the end they invented some natural inclusions with impurities such as iron, nickel, sulfur and carbon.
From the point of view of the important part of the wrap, the large diamond should be formed in the case of liquid metal, which is completely different from the composition of the small diamond.
According to the researchers, large diamonds are much deeper outside the Earth than most diamonds. Their depth can be 400 to 750 kilometers, while the rest of the natural diamonds are generally 150 thousand. The rice is composed of a depth of 200 kilometers. At first these large diamonds rose to high altitudes following geological movements such as volcanic eruptions.
In addition, because large diamonds are formed in the case of liquid metal, and nitrogen is received by the metal, so that the purity of large diamonds is also high. The vast majority of diamonds can be formed in the silicate case by the rest of the chemical reaction, so that the diamonds that are made up of 150 to 200 kilometers are easily wrapped with more nitrogen, and the purity is absolutely lower.
Why is it that giant diamonds are rare? Because it is not deep enough.
