The difference between diamond and diamond, is diamond a diamond

Diamond is a natural mineral, and it is also a mid-block gemstone in its own right. Colorless and transparent zircon is a good substitute for diamonds when carefully crafted. The refractive index of a diamond is close to 2, and the dispersion is similar to that of a diamond.

Therefore, in appearance, the diamond will also sparkle with colorful brilliance, which is very similar to a diamond.

Diamond has a strong birefringence, i.e. it has two refractive indexes, and the difference between the two refractive indices is large. As a result, a very special optical phenomenon is produced, when the finished zircon is observed with a magnifying glass, it can be seen from the top surface that there are obvious double shadows on the bottom surface and the ridgeline. Because diamonds are "homogeneous", there will never be a double shadow.

1. The difference between diamond and diamond, diamond is a mineral substance composed of pure carbon, that is, the rough diamond.

2. Diamond is a mineralogical name, while diamond is a gemological name.

3. Diamonds are diamond gemstones that have been polished into jewelry, and rough diamonds that have not been valued by tools are called gemstone diamonds.

4. Diamonds have gone through complex processes, such as cutting, polishing, etc., and such fine work consumes a lot of manpower and material resources, so diamonds are higher than diamonds.

Diamond refers to polished diamond, which is a natural mineral that is the rough of diamonds. To put it simply, diamond is an elemental crystal composed of carbon that is formed under high pressure and high temperature conditions in the deep part of the earth. Human civilization.

Although it has a history of thousands of years, it is only a few hundred years since people discovered and first understood the diamond, and the time to truly uncover the inner mystery of the diamond is even shorter. Until then, it has been accompanied by mythical religious cults and fearful legends, as well as symbols of bravery, power, status, and honor. Today, diamonds are no longer mysterious, nor are they just for royalty.

It has become a popular gem that people can own and wear. Diamonds have a long history of culture, and today they are seen more as a symbol of love and loyalty. The quality of a diamond can be determined from the following four aspects:

Color, clarity, cut and weight.

To be precise, diamond is a solid carbon material found in nature, while gemstone diamond is a gemstone made by polishing diamond. The difference between the two is quite large (although they are more expensive), mainly because the diamond consumes a lot of manpower, material resources, financial resources and time in the grinding process. Since diamond is the hardest substance in the world, it can sometimes take several years to cut and polish a large piece of diamond to the desired shape and quality.

One of the main reasons why diamond is used to make gemstones, that is, diamonds, is because of its hardness, it will not be scratched by any other material, so it can retain its luster very well.

On the other hand, it is also because diamond has strong dispersion properties, it can disperse white light into colorful light very well, which is also one of its biggest charms.

There are two types of diamonds, natural diamonds and synthetic diamonds.

In the case of natural diamond, it can be seen from the above introduction that in order to form a diamond structure, the carbon atoms need to be "squeezed very tightly". Obviously, this requires a lot of pressure, in addition, enough energy to restructure the carbon atoms, so natural diamonds are often formed in an environment of high temperature and pressure.

In order to achieve this condition, most of the diamonds are formed 150-250 kilometers underground, and their formation time is about 1 billion to 3.5 billion years, which shows the preciousness of diamonds. They were brought to the surface by volcanic eruptions hundreds of millions of years ago, so humans had the opportunity to exploit them.

At present, there are two methods of synthetic diamond, one is to simulate nature for high temperature and high pressure synthesis, and the other is to use chemical vapor deposition method for synthesis. The diamond synthesized by both methods is mainly used in industry, such as cutting tools, diamond coating (wear and corrosion resistance), as a polishing powder, etc., and the current technology is still difficult to synthesize a continuous whole like natural diamond in a short period of time, and commercial diamond with gem value.

Diamonds are diamonds. Diamond Diamond, commonly known as "diamond", is the rough diamond, which is a mineral composed of the element carbon. Diamonds, on the other hand, are rounded, cut and polished, and are essentially the same substance, just like wood and furniture.

Diamond is commonly known"Diamonds", which is a mineral composed of the element carbon, is the hardest of the many natural minerals currently found on Earth. Diamond is used in a wide range of applications, such as cutting tools in industry and industry. Diamonds, on the other hand, are diamonds that have been polished and processed, and are products that are refined from diamonds.

Therefore, diamond is the rough diamond, and the relationship between the two is equivalent to that between wood and furniture.

Their relationship is the same as that between wood and furniture. Some people say that diamonds are diamonds, but this statement is completely wrong. Diamonds are simply diamond-refined products; Diamond refers to polished diamond, which is a natural mineral that is the rough of diamonds.

To put it simply, diamonds are wood, and diamonds are furniture. Extended information: Diamond is commonly known as"Diamonds"。

It is a mineral composed of carbon elements, a particle substance composed of elemental elements in nature, and a carbon allotrope (diamond, graphene, fullerene, carbon nanotubes, blue silk stone, etc.). Diamond is the hardest substance among the many natural occurrences found on the earth, and diamond is not only produced on the earth, but also in the meteorites that have fallen on the celestial body. Diamond is used in a wide range of applications, such as:

Cutting tools in crafts and industry.

Questions. I disagree.

What do you disagree with.

Diamonds, also known as diamonds, are the same thing, the hardest stones on the planet today.

Alrosa, Russia's main miner, is responsible for about 90% of the country's diamond mining. Due to Russia's huge diamond reserves, they are able to produce diamonds of all sizes, shapes, and colors, which makes them highly sought after by countries around the world.

1. Different forms

Diamonds are rough diamonds, while diamonds are diamonds that have been polished. In addition, diamond is the scientific name of mineralogy, which is essentially a natural mineral that is only processed by physical means such as mining, cutting, etc. Diamonds, on the other hand, are gemstones that have been carved and are treated by a variety of processing methods such as cutting, polishing, and polishing.

2. The processing technology is different

From the perspective of diamond and diamond processing technology, diamond often only undergoes physical treatment methods such as mining and cutting, while diamond will be treated by cutting, polishing, polishing and other processing methods.

3. The refractive index is different

Diamond and diamond have birefringence, that is, have two refractive indexes, because the refractive index difference is relatively large, at this time with a magnifying glass, you can see that the bottom of the surface and the ridge line have obvious double shadows, diamonds because it is a "homogeneous", there will be no double shadow phenomenon.

4. Different uses

Diamond has excellent mechanical, optical and thermal properties, and is widely used in industry, and it is more commonly used as a cutting tool.

Diamonds can be used as ornaments, jewelry, or collectibles, diamond jewelry is not only durable, not afraid of burning, but also dazzling, sparkling, in addition to being used in industry to cut glass drill bits and mining caverns on industrial probes.

Difference Between Diamond and Diamond:1. Different forms

There is a difference between the form of diamond and diamond, diamond is actually the rough of diamond, it is a mineral composed of pure carbon, and diamond is a diamond that has been polished, and it will be more beautiful on the outside.

2. The definitions are different.

Diamond is actually a mineralogical name, and its essence is a natural mineral. Diamond, on the other hand, is a gemstone that has been carved and formed.

3. The processing technology is different.

From the perspective of diamond and diamond processing technology, diamond often only undergoes physical treatment methods such as mining and cutting, while diamond will be treated by cutting, polishing, polishing and other processing methods.

Diamond and diamond are the same, diamond is the rough of diamond, diamond can become diamond after processing, they are very hard substances, diamond can also be used in the industrial cutting industry, made into a variety of cutting tools.

Diamond and diamond have birefringence, that is, have two refractive indexes, because the refractive index difference is relatively large, at this time with a magnifying glass, you can see that the bottom of the surface and the ridge line have obvious double shadows, diamonds because it is a "homogeneous", there will be no double shadow phenomenon.

Identification method:1. Observing with the naked eye, you can see that the diamond can scatter a very obvious colorful luster.

2. It is not true that if you drop a drop of water on it, the water will disperse immediately.

3. Take a breath, the fog takes a long time to evaporate, which is fake.

4. Grind it with sandpaper on diamonds and diamonds, if there are no scratches.

The above is to introduce the difference between diamond and diamond, I hope to help you.

Diamond is a kind of elemental crystal composed of carbon elements formed under high pressure and high temperature conditions in the deep part of the earth, which refers to diamonds that have been polished. Diamond is a colorless octahedral crystal composed of pure carbon, which is linked by carbon atoms with tetravalent bonds, and is the hardest substance known to exist in nature. Because the C-C bond in diamond is very strong, all the valence electrons are involved in the formation of covalent bonds, there are no free electrons, so the diamond is very hard, the melting point is 6900 degrees Fahrenheit, the ignition point of the diamond is 720 800 in pure oxygen, and 850 1000 in the air, and it does not conduct electricity.

The Bernat brothers discovered the Kimberley diamond mine in 1870. It was this discovery that made it known which rocks could contain diamonds.

It turned out to be a volcanic rock formed after the magma cooled down in ancient times. Later, the researchers found that in addition to diamonds, the volcanic rock also contains two minerals called garnet and olivine. Therefore, in those locations where garnet and olivine are found, there is a relatively high probability of finding diamond mines.

As a result, garnet and peridot became the "indicator minerals" for finding diamonds.

The method of finding diamond ore according to the indicator minerals did not come out of nowhere on any given day. In the 70s of the last century, John Jani, a geochemist at the Smithsonian Institution in the United States, published his findings after carefully studying the relationship between garnet and diamonds. But before that, in the '50s, De Beers' geologists were already looking for diamond mines around the world according to the indicated minerals.
