Is this diamond? Is there any value?

What is diamond, what is the difference between it is from diamond?
Mu diamonds can be said to be a household name, and immediately think of various diamond rings, diamond necklaces and other jewelry. But when it comes to diamonds, some people may be more unfamiliar. Thinking more may be diamond diamonds.
The saying is called "don't take porcelain to live without diamond diamonds." Everyone knows that ceramics are very hard. In fact, its hardness is much higher than everyone thinks (hardness can reach more than 5 times that of general steel). Now there are many ceramic knives on the market. It can be seen that it is impossible to get drilling on the ceramics. Generally, the diamond drill is often used. At this time, diamond diamonds are often used. Diamond diamonds are a processing tool with diamond as the drill.
It that here, you need to talk about diamonds carefully.
What is diamond?
Academic speaking, Diamond is a solid form of carbon element. Each carbon atom is connected to the four carbon atoms around the form of common price bonds to form a structure of a positive tetraon. It sounds stunned? Look at the figure below.
This combination (lattice) enables carbon atoms to accumulate in the most close way, thus diamond the most atomic density and the highest hardness in the world. In fact, this is like we are playing with mud. The tighter the mud is, the harder it is.
What is the difference between diamonds and diamonds?
It, Diamond is a solid carbon material in nature, and Diamond (Gemstone Diamond) is a gem formed diamond. The price difference between the two is large (although both are more expensive), mainly because diamonds consume a lot of manpower, material resources, financial resources and time in the process of polishing. Because diamond is the hardest material in the world, it is necessary to cut and polish the large diamond raw material to the ideal shape and quality, and sometimes it takes several years.
Itdae stone will be used to make gems, that is, diamonds. One of the main reason is that because of its hardness, it will not be scratched by any other materials, so it can retain its own gloss well.
The on the other hand because diamond has a strong scattered characteristics. It can spread the white light into colorful light, which is one of its biggest charm.
Whats of diamonds come from?
The diamond stone is divided into two types, natural diamonds and artificial diamonds.
For natural diamonds, the above introduction can be known that in order to form diamond structure, carbon atoms need to be "squeezed tightly". Obviously, this requires a large pressure. In addition, enough energy is required to reconstruct carbon atoms, so natural diamonds are often formed in high temperature and high pressure environments.
In order to meet this condition, most diamonds are formed by 150-250 kilometers underground. The formation time is about 1 billion to 3.5 billion years. About hundreds of millions of years ago, they were brought to the surface as the volcanic eruption, so humans had the opportunity to minimize.
The artificial diamond currently has two means, one is to simulate the natural world for high temperature and high pressure synthesis, and the other is to synthesize the use of chemical gas deposition method. Both methods synthesized diamonds are mainly used in industries, such as cutting tools, diamond coating (wear resistance and corrosion), as polishing powder, etc. At present, it is difficult to synthesize in the short term like natural diamonds as a continuous overall as a whole in the short term. For commercial diamond with gem value.
If artificial diamond
Tracka -coating cutting tools are widely used in the processing of aerospace materials
must diamond stone be colorless and transparent?
not necessarily, depending on the impurities in diamonds. Of course, it is not to say that there is a bad diamond stone, but some impurities can increase the value of diamonds.
For example, if some carbon atoms in diamond are replaced by boron, then it is blue and transparent, which can be made into blue diamonds; and if some of them are replaced by nitrogen atoms, it will become yellow transparent Vajrayana.
This diamond (the world's largest blue diamond, 45.52 carat (9.104 grams), is now in the National Natural History Museum of the United States)
transparent. There are also pink, purple, red, etc.
In 2008, a blue diamond named Wetz Bus, weighing 35.56 carats (1 carat is equal to 0.2 grams), and sold at the auction house for $ 24 million.
Vetus bus diamond
In 2009, another blue diamond weighing 7.03 carat was auctioned to $ 9.5 million. In the same year, a 5 -carat pink diamond was shot in Hong Kong for $ 10.8 million, creating the highest price of diamonds in history.
On how to identify diamond or diamond?
The simple method here:
1. Gently grind with sandpaper, the scratch is fake;
2. Drop a drop of water on it, if the water is dispersed immediately, it is fake.
3. In the face of it, it is fake if it evaporates if the fog has been evaporated for a long time. , So the real diamond can scatter the very obvious colorful luster.

There are many types of diamonds in the world, but large, colorless or fancy flawd diamonds are very rare. These are actually investment -level diamonds. The most worthy diamonds are high -priced and rare diamonds. They are defined by 4C: cutting, color, carat and clarity. Based on all aspects of conditions, Russia's diamonds accounted for great advantages in terms of cost -effectiveness.
