The largest diamond 10, the largest diamond

Diamonds are graded, there are abrasive grades, there are gem grades (the highest grade), diamonds are the best in diamonds, most of them are natural, the world's largest naturally occurring diamond is the "Cullinan" diamond found in the Premir diamond mine in South Africa in January 1905, known as the "Star of Africa", weighing 3,106 carats. 1 carat is equivalent to a gram, and you can estimate its weight. The largest diamond in our country is"Golden Rooster Diamond", heavy carat, plundered by the Japanese invaders, and his whereabouts are still unknown.

The largest preserved in our country at present is"Jolin Diamonds"--- carat, millimeters long, pale yellow in color, now preserved in People's Bank of China.

Most of it is located in Africa, which accounts for more than 50% of the world's total.

1. Africa is the place with the largest diamond reserves in the world. South Africa is the world's major diamond producing area, producing many world-famous diamonds, such as Cullinan 3106 carats of stupid slag, noble carats, Janger 726 carats and so on.

2. Other diamond-producing areas. In addition to Africa, Russia, Australia and Canada are also world-renowned diamond-producing regions.

Hello, diamond is a type of carbon that has been transformed over many years.

How hard is the diamond.

It is a natural mineral and the main synthetic material of diamonds.

What does diamond look like.

Diamond has a hardness of 10, which is the hardest substance in nature; It is luminous, and can reflect and refract light cyan phosphorescence after being irradiated by light; Its chemical properties are very stable, and it is insoluble in acids and alkalis at room temperature.

Hello, the above ** is the diamond that has just been unearthed.

After processing, diamond becomes brilliant and is the best material for decorative objects.

Diamond: Definition:

The allotropic of carbon is an excitable form, and there are two types of natural and man-made.

The diamond is commonly known as the "diamond diamond". It is often referred to as diamond, which is a mineral made up of pure carbon. Diamond is the hardest substance in nature. Diamond is very versatile.

For example: cutting tools in crafts and industry. Carbon can form diamonds at high temperatures and pressures.

Diamond is commonly known as "diamond diamond". [1] Pure diamonds, so-called diamonds, are a natural mineral that is the rough of diamonds. Diamonds are elemental crystals composed of carbon formed under high pressure and high temperature conditions in the deep part of the earth.

In diamond crystals, carbon atoms are connected to each other by tetrahedral bonding to form an infinite three-dimensional skeleton, which is a typical atomic crystal. Each carbon atom forms a covalent bond with four other carbon atoms in a sp3 hybrid orbital to form a regular quadrilateral, which is often referred to as a diamond. Diamond is the hardest substance in nature.

Natural diamonds are produced in small quantities and are often hidden deep in the earth. It is only at very high temperatures and enormous pressures that the carbon in underground lava can form expensive diamonds through a natural crystallization process. Due to the low production of natural diamonds, it is expensive.

Ultra-high temperatures and pressures are commonly used to make synthetic diamond.
